Having trouble writing a regular expression to restrict inputs for a text field. I would like to restrict the values to xxxxx-xxx where the "x" are integers. From what I understand, {n} limits to "n" number of values (5 & 3 in this case), however when testing in the form preview, the constraint is satisfied as long as there are "n" or more values. Is there something I am missing? I have attached my excel file, and included my expression below. Any help is much appreciated.
regex(.,'[0-9]{5}'+'-'+'[0-9]{3}')
