I have a gallery with buttons that display Series 1 information from a SharePoint list. On Select these buttons set varSelectedSeries to the selected Series 1 (Example: varSelectedSeries=0100).

There is another SharePoint list with Occupations that filters on varSelectedSeries as shown below. In this example you can see all of the Series 1 are showing.
| Occupations |
| Series 1 | Series 2 | Job Title |
| 0100 | 0110 | HR |
| 0100 | 0120 | Manager |
| 0100 | 0130 | Nurse |
| 0103 | 0140 | IT |
| 0104 | 0150 | Maintenance |
Finally there is an existing SharePoint list of applicants but the applicants only have an Occupation name and that is a choice/lookup column that feeds from the Occupation list. What I am trying to figure out is how do I get a collection to pull all of the applicants that have HR for an Occupation based on a variable set to 0100?
| Applicants |
| Name | City | Occupation |
| Joe | Chicago | HR |
| Bob | New York | HR |
| Jeff | Atlanta | Manager |
