Make a combo box based on continent selected

Hello,

In html template i use  [var.tmpl_CONTENT;htmlconv=no;protect=no]

tmpl_CONTENT is a vaiable ,  which carries an html snippet

html snippet is as follows:

<select id="input_region" name="input_region">
<option  value="[onshow.regioncode1]/">America</option>
<option  value="[onshow.regioncode2]/" selected="selected">Aisa</option>
</select>

I assign values regioncode1 and regioncode2 on php page before $TBS->LoadTemplate statement
But the page is not recognised these two vaiables, it displyed [onshow.regioncode1] and [onshow.regioncode2] on the web page source.
The Var parameter not recognise onshow and onload placeholders ..
Could you please help me for finding a solution.. Thanks

If $regioncode1 and $regioncode2 are defined before the template is loaded, then you an replace
[var.tmpl_CONTENT;htmlconv=no;protect=no]
with
[onload.tmpl_CONTENT;htmlconv=no;protect=no]

Then it should be correctly merged.

Thanks a lot.. It is working....
