Question

Is it possible for one form value to reference another currently selected form value upon form submit ?

Take this form as an Example:

<form name="name" action="%SCRIPTURLPATH{save}%/%WEB%/" method="post">
<input type="text" name="firstvalue" size="38" maxlength="36" /> 
<input type="text" name="secondvalue" size="38" maxlength="36" /> 
<input type="hidden" name="topic" size="38" maxlength="36" /> 
<input type="hidden" name="templatetopic" value="SomeTemplate" />
<input type="submit" class="twikiSubmit" value="Create Project Page" />
</form>

I would like to be able to submit the form (upon button click) with the value for the 'name' input equal to the 'firstvalue' input concatenated with the 'secondvalue' input.

I realize that in some cases the template topic could do the concatenation, but this is not possible for topic creation or to populate a template topic form field.

Please help.
