I recently made a change on a form that is now resulting in this error message upon submit:
The function 'LEN' was given an invalid number of arguments.
This form has been working perfecting for a number of years. The applicant needs to add a long-legal address OR a rural address. Occasionally, the applicant will enter too many digits in the first part of the long-legal address and then the form will not save to Laserfiche because of a constraint on the field.
I recently changed the first part of the long-legal address (a collection field) to be a drop-down pick list instead of free-form, to force the applicant to only pick valid formats. This is working perfectly.
The problem that we discovered today is that the form now is confused if the applicant only fills in the rural address and does not attempt a long-legal address. I have double checked to make sure I didn't turn on the Required option. I did not. And yet, this error is coming up only when the applicant leaves the legal address options blank.
I did see on another post that someone who got this error resolved it when he discovered that the changed piece did not have a variable name, however, mine does have a variable name.
