Thanks for the reply Mike. I am the BIGGEST IDIOT. What I meant was
[!do_once]. I am STUPID!!

I need code that will SKIP the first iteration!! Actually your reply
made me think, and I remembered that prefix-change will take a
[else][/else] pair thus:

[stk-change 2][condition]1[/condition]
	<!-- no output for first -->
 [else]</table>[/tabbed-panel][/else]
[/stk-change 2]

More importantly I realized that these will nest!!! I would guess the
above is more efficient than:

[if explicit]
[condition]
$num = '[stk-increment]';
return 1 if $num eq 1;
return 0;
[/condition]
[else]</table>[/tabbed-panel][/else][/if]

And it sure is cleaner :) I should have tried this first, I guess I had
some sort of mental block becuase the [else][/else] is documented..
sorry for cluttering the archives.

Thanks!
