Thank you again bananalive, it worked exactly as I asked. You Da Man!

However, I didn't think it through all the way.
What I really needed was if 'any' of the three question were used, then the other two would have to be filled in too.

So I just repeated the code and changed the q#'s around like this

if ($q[4] && (empty($q[5]) || empty($q[6]))) 
        { 
            $complete = false; 
            if (empty($q[5])) $iqs[] = 5; 
            if (empty($q[6])) $iqs[] = 6; 
        }  
if ($q[5] && (empty($q[4]) || empty($q[6]))) 
        { 
            $complete = false; 
            if (empty($q[4])) $iqs[] = 4; 
            if (empty($q[6])) $iqs[] = 6; 
        }  
if ($q[6] && (empty($q[4]) || empty($q[5]))) 
        { 
            $complete = false; 
            if (empty($q[4])) $iqs[] = 4; 
            if (empty($q[5])) $iqs[] = 5; 
        }

and it works ok.

But I'm wondering if this is the proper way to do it for each set of questions, or if it should be written a different way.

Thanks again for your help. *nominated for Mod of Month*
