with vbscript, it can be done using the 'form.submit' command. You can write it directly, into your page, i think, like below:
Then, in your form code, write:
Private Sub SubmitForms()
Correct me if I'm wrong, guys, but I believe this should work. I am a little rusty on syntax, though, so I would get a second opinion if I was you. Also, I'm unsure of the "VBScript:SubmitForms()" line. You may be able to just say "SubmitForms()".
<INPUT TYPE="BUTTON" onClick="VBScript:SubmitForms()">
Good luck with your scripts!
