The helper file corrects the default file value glitch. I have everything working fine on the website I was originally having problems with but on website 2 one all the form will do is write the default value. It doesn't upload anything. I built another form in CS3/DFP1 for website 2 and it works properly with the same table and the same folder.
I too have projects to complete and can't spend any more time on this.
Hopefully WA will issue a dot release soon.
