>All I do is bring up the form, choose, in my case, a Project, then go to the Properties page and in a Required field I select the existing letters WFBCI and delete them, not knowing this is a 10 character field and there are still 5 spaces remaining. I then click the Save button and the changes save with the blank field. I put in the .trim() and the rule catches the above and indicates it is a required field.

OK, I got it. I will run through that and see what is happening. I take it your field is a set length rather than Varchar type and it causes the whole length to have data even if padded with space. I would have expected the method to catch the spaces and take those off before saving it.
