Blank or Whitespace validation

[emilytan]

Hi,

I have a mandatory Text field with the following validation rule formula.

Visitor1=='' && (isNullOrEmpty(trim((Visitor1FirstName))||Visitor1FirstName =='') && (Visitor1LastName!='' || Visitor1Organisation!='')

The validation should work like this: if the drop down (Visitor1) is not selected then Visitor1FirstName and Visitor1LastName and Visitor1Organisation should not be empty. [See below Image]

It work perfectly, if the these three fields were empty when Visitor1 is not selected. However, if a space was entered to any of these fields, somehow it ticketed the blank space as a value and bypass the validation.

So how to validate the blank or whitespace in Nintex form Text field?

Thanks,

Emily

can you add trim to all three textboxes in your rule?

Did you ever get this to work? I am having the same problem, REFERENCE:  

The TRIM worked but only some of the time. I am not sure what made it work sometimes and then not others. As a test today I removed the TRIM from one of the choices to see if the behavior changed and it did, the validation itself now work vs working in a very odd way. It would accept 1/2 of the form filled in and let the second 1/2 bypass and let the form save. It was as if the section were separate.
