How to convert multi-select options into text string for dynamic lookup

Hey all, new to airtable and unfortunately the community is down. I’m looking for a way to convert multi select options into text string for dynamic lookup. Ultimately I want to find records with matching variables from two tables - where table 1) is the input table from a form, and table 2) is an existing database. TIA!

Not sure what you mean. Are you trying to do dynamic filtering of linked record fields? That requires linked record fields (not multi-select fields), and it is explained in Airtable’s support article here.
