In this video we cover 5 common Excel lookup problems: 1. Lookup returns an error (#NA) – This is a common problem with VLOOKUP. If the VLOOKUP function returns #NA it is likely because the item you’re looking up does not exist on the lookup table. The solution so far has been to wrap the VLOOKUP function inside IFNA or IFERROR functions. With XLOOKUP however, you no longer need to do that. You just need to use the 4th argument of XLOOKUP [If_not_found] optional argument and specify the value you’d like to get back if the value does not exist on the lookup array. 2. Horizontal lookup – In legacy Excel when we needed to lookup a value in a table that was structured horizontally instead of vertically we would use the HLOOKUP function. The new XLOOkUP function can do horizontal lookups as well. You just have to select the horizontal array instead of the vertical array. 3. Look for a partial match instead of an exact match in Excel: There might be times you need to look for a partial match. In this case you can combine wildcards such as the asterisk or question mark characters and combine them together with the 5th argument of XLOOKUP which is the optional [match mode] argument. 4. Two way Excel lookup: To look up a value on the rows as well as columns we generally combined VLOOKUP with Excel Match function or used the famous INDEX & MATCH functions. We no longer need to use two separate functions to do a two way lookup. We can use XLOOKUP inside another XLOOKUP to get the job done. The advantage is we just need to know one function well, instead of combining different Excel lookup functions with one another. 5. Excel approximate match lookup: There are times you’d like to look for a value inside a data table and return the closest match. This is specially used for cases where you have thresholds for example for bonus schemes. If a number falls between a specific threshold you’d like to return a corresponding value. This is where you can use XLOOKUP’s 5th argument [match mode] to look for “exact match or next smaller item” or “exact match or next larger item”. Course Length: 13:33 minutes Source: Leila Gharani

Co-operative education is a three-way partnership between the university, students and employers. Students apply their classroom knowledge in a series of four-month work experiences. You, the employer, enhance a student’s education, while reaping the unique benefits of CO-OP employees.
- Year-round access to well-motivated, qualified employees.
- Access to potential full-time staff in a controlled environment, reducing your costs and risks.
- Access to a cost-effective source of temporary employees for peak periods or special projects.
- A say in what students learn by working with the university.
- Promotion of your organization as one that believes in developing the potential of young people.
- Access to a great pool of French-speaking, English-speaking and bilingual students.
Most work terms run at least 15 weeks, or four months. They can be no shorter than 13 weeks. Some master’s students, as well as some science and engineering students, are available for 8 or 12 months’ work terms.
All jobs are reviewed by a CO-OP Program Coordinator, and only those providing students with work experience related to their professional development are approved. Administrative activities involved in a job should be less than 10% of the entire workload.
When you first contact SSC, you are assigned one of our Program Coordinators, depending on your discipline of interest. This person is your main contact in our office. As you move through the recruitment process, you also work with a representative from CO-OP Administrative Services, who assists with job posting and interview scheduling.
Internships offer usually one discipline-specific, supervised, structured paid or unpaid, and for academic credit work experience or practice placement.
Work Experience intersperses one or two work terms (typically full-time) into an academic program, where work terms provide experience in a workplace setting related to the student’s field of study and/or career goals.
Community Service Learning (CSL) integrates meaningful community service with classroom instruction and critical reflection to enrich the learning experience and strengthen communities. In practice, students work in partnership with a community-based organization to apply their disciplinary knowledge to a challenge identified by the community.
Field Placement provides students with an intensive part-time/short term intensive hands-on practical experience in a setting relevant to their subject of study. Field placements may not require supervision of a registered or licensed professional and the completed work experience hours are not required for professional certification. Field placements account for work-integrated educational experiences not encompassed by other forms, such as co-op, clinic, practicum, and internship.
