Hi @Jack_Cooney - If the lookup field is a currency (or number) in its origin table, then you should just be able to add it to another currency field in the 2nd table:

Here my total is:
Price + Currency
(then total is formatted as currency).
A couple of things you could check
- is the lookup field a number/currency in its table?
- What is the IF statement you are using? If the statement gives out mixed results, e.g. a number in one scenario and text in another, this could be the issue
Thanks for the response. I was able to solve the issue by using BLANK() in my IF() statement instead of IF(TRUE,“X”,""), which must’ve allowed the field to be considered a number instead of text. I appreciate the help, too @kuovonne
