trying to call several templates

I'm trying to call several files for my template.
I use the following code but does not work. The block does not read my files.
How can i access variable templateArray to load it as template?
[onload;file=[templateArray.val]] (i know this one does not work.. help please..)
any help would be appreciated

----------------------------------------------
require('tbs_class_php5.php');
$templatefile = array('content1.htm','content2.htm');
$tbs = new clsTinyButStrong;
$tbs->LoadTemplate('templates/main.htm') ;
$tbs->MergeBlock('templateArray',$templatefile) ;
$tbs->Show() ;
----------------------------------------------
[onload;file='header.htm']

[templateArray;block=begin]
[onload;file=[templateArray.val]]
[templateArray;block=end]

[onload;file='footer.htm']

Hi,

Replace:
  [onload;file=[templateArray.val]]
With:
  [onshow;file=[templateArray.val]]

And it should work.
The [onload] tags are processed before you call the MergeBlock() method. So paremeter "file" has not the exected value when the tag is processed in your snippet.

It works now.
Thank you so much for the info master Skrol29.
