Not sure this is what you are looking for, but here it goes:

I assume you have two fields in your form, like this:

<form action="foo_dtml" method="POST">
  <input type="text" name="x">
  <input type="text" name="y">
  ...
</form>

Then, in foo_dtml, you would display them as:

<dtml-var x> <dtml-var y>

Easy so far.

I think this is what you are looking for:

<dtml-let varname=" 'therealvar' + 'name' ">
  <!-- varname should now be equal to 'therealvarname' -->
  <dtml-var varname>
</dtml-let>
