How to: Show dialog box after form is.......

Anyone who knows how to make a confirmation/dialog box saying that the form has been sent to the admin? Like a MsgBox in VB saying that "Thank you for your interested. Your inquiry has been sent to the administrator."

-thanks~

Forms Management > Form Code > On Submit code - after sending email: > Thank you for your interested. Your inquiry has been sent to the administrator.

This?

Forms Management > Form Code > On Submit code - after sending email: > Thank you for your interested. Your inquiry has been sent to the administrator.

Thanks dude! I never thought it would be this easy.
