Great solution I love it, trying to get my current company to invest in this.
I am looking at your trial and I noticed an error (see attached) that I cant figure out. I am using DFFS on two lists, A and B. A is the list that uses vLookup to List B. I have a value passed to a field in B and use your solution to hide that field on the new form. This is working correctly and the form and your tool appears to be functioning correctly however I only receive this error message when I click new item from the vlookup of List A. If I go to List B and click new item the form works fine with now error.
