JS in ZP; Cannot test indexOf array

[txseo]

test = flds_Exist.indexOf(fieldNames);
return test;


That should return a '-1' to the variable but does not.

test = flds_Exist.indexOf(fieldNames);
return test;

Why should it return "-1"? Could you please give full example?

Vlad, thanks for responding. I later figured out that a misplaced period was throwing an error prior to this call.
