As another recent immigrant, welcome to planet Zope. If you think your brain
is rewired now, wait till you experience the 'lightbulb effect' of
acquisition! :)

I think you need to do a level of indirection to get to your goal. In the
first instance (frameset) you want the contents of title_src. You get that
via <!--#var title_src--> (as you said). In the second instance, you want
the contents of the variable whose name is given by the value of title_src
(I think that you should make title_src a property BTW).

something like

<table>
<tr>
<td colspan=2>
<!--#var "_[title_src]"-->
</td>
...
</tr>
</table>

should work - well it did on my box! :)
