So the form could look like this: This sort of dynamic content isn't easy to do with web pages. One option I might suggest would be to provide a box where the user can enter how many groups of Lines 1 to 3 they plan on entering. That way, your form can generate the desired number of lines. It's not a very elegant solution from a UI standpoint, of course. I don't know if there's a better way with DHTML or somesuch, but it'd surprise me. :) Anyway, the code for that suggestion would simply be a for loop that spits out the number of for fields desired. $fieldCount reflects how many groupings of Lines 1 to 3 they want. for( $i = 0; $i < $fieldCount; $i++ ) { ?> Line1: <input type="text" name="line1[]"><br> Line2: <input type="text" name="line2[]"><br> Line3: <input type="text" name="line3[]"><br> <? } Which will make three arrays of fields. So your first grouping would be $line1[0], $line2[0], $line3[0], the second $line1[1], $line2[1], $line3[1], and so on. HTH, Matt
