Hey there, I just tested this out a bit more and seems not to work.
This is what i'm putting inside the Look up field and it only ever matches to the first job posting.
outputs('Get_items')?['body/value']?[0]['ID']
i.e
ID Job Posting
1 Tech Director
2 IT Consultant
If user enters IT Consultant in the micorsoft forms, it always pulls Tech Director. Am i doing something wrong?
