PHP Code:
<form name="spell_form" id="spell_form" method="POST" target="spellWindow" action="vbspell.php">
<input type="hidden" name="spell_formname" value="">
<input type="hidden" name="spell_fieldname" value="">
<input type="hidden" name="spellstring" value="">
</form>
code to the newthread template for example, the mod works fine...for the most part. Hope this helps others...
