I'll work on it with you via pm. Everything looks okay, if it's blank then the function is working except it's not inserting the $formpost template correctly

Try changing
eval("\$formsend = \"".gettemplate("$formpost")."\";");

to

eval("\$formsend = \"".gettemplate("formpost1")."\";");

PM me if you have problems and it still isn't working. Make sure (just double and triple check ) formpost1 template is in the current style set you're using
