We typically don't open other forms from within our forms, but in this particular form, I had buttons on a view that appears later in the process (not the ones I was working on). I just had to keep looking because clicking on the error didn't take me to where I needed to go and if I looked in the code, I wouldn't have known what to look for. Sooooo, yes, I had a button that used the "Open a new form to fill out" feature. It was a legitimate error, but worthless in helping me find it to address it.
I do have a design checker error that prevents it from completing and possibly helping, but that's another story. Thanks all.
