I already explained this to you on the NMS support list, but just for the record I'll say it again here. It is relatively trivial to have a form with hidden fields which can be populated by Javascript, you can have FormMail as the action of the form and have the Javascript automatically submit the form, sending all of the content of the hidden fields to FormMail which will then send it on in an e-mail, if you wish you can suppress the output of the confirmation page. If you want help with the Javascript part of this then you are probably better asking Somewhere else.If you have questions specific to the installation and configuration of the NMS FormMail then you should post those on the NMS support list.
