Check list for another sheet populated by forms fuctions

i have sheet which is populated through forms function

i want to create another sheet as a check list which i want to track which locations the forms have been completed.

one of the fields in the forms is location, so in my check list sheet im trying to do like a if + vlookup on the location column

if it appears in the sheet (populated by forms) i want to automate a yes result from the if function

any advice please
