Form not submitting
I have this form I built here. contact.php I didn't build the site, just built the form. It's hosted on the same server my site is so I know that isn't an issue. I had them update the version of PHP to PHP5+. When the form is filled out and submitted the URL changes to this contact.php?invalid=true I can't figure out if it's Universal E-mail or CSS Form Builder.
Can someone look at it?
