The Allaire documentation for some of the functions is pretty unclear, isn't it?&nbsp;&nbsp;The evaluate() function is used when you find yourself with nested pound signs.<br><br>In many cases, I've wanted to display a form in which part of a field name is itself a variable:<br><br>&lt;CFLOOP INDEX=&quot;R&quot; FROM=&quot;1&quot; TO=&quot;5&quot;&gt;<br>&lt;INPUT TYPE=&quot;Text&quot; NAME=&quot;Field#R#&quot; SIZE=10&gt;<br>&lt;/cfloop&gt;<br><br>On the next page when you want to get to the value of each field you use evaluate:<br><br>&lt;CFLOOP INDEX=&quot;R&quot; FROM=&quot;1&quot; TO=&quot;5&quot;&gt;<br>&lt;CFSET foo = evaluate(&quot;Field#R#&quot&gt;<br>&lt;/cfloop&gt;<br>
