[NSFW] Comparing two fields (if not empty)

Hi CodePeople!

I have two currency fields (fieldname1 and fieldname2) and a calculated field (fieldname3). I want to compare the entries of the currency fields (only if these are filled):

fieldname3 => IF(fieldname1|r === fieldname2|r),1,0)

This works nice, however, when I want to put it into the following function, empty currency fields are treated as “0” and therefore result in 1:

(function() {
if (fieldname1 !== “” && fieldname2 !== “” && fieldname1 === fieldname2) {
return 1;
} else {
return 0;
}
})();

What can I do?

Thank you!
