CMS Made Simple Forums

I have installed formbuilder 0.4.3 and cmsmailer successfully . CMSmailer gives Email test O.K. Even though formbuilder show " error in handling form submission".
Is there any extra setting for formbuilder to remove this error.
Please help.

You have the email link submission in the first field of the form, the one where you set the email it's supposed to be sent to?...
