If I'm following you correctly, The formfields will have different names but will be the forth formfield on each document.

So, If im still in the ballpark, form1, formfield four, will be the first paragraph, followed by form2, formfield four, will be the second paragraph, so on and soforth.

If this is correct this will work great. Will the text from formfield 4 on form1 be placed under RE: with a space at the end of the text, followed by Form2, formfield four, with a space at the end of that text, followed by any additional forms.

Hope this make sense. I'm starting to get confussed!!!
