Code (markup):

onsubmit="checkforblank()"

Code (markup):

it does seem to work just fine, it pulls the pop up message but when you hit okay. it takes them to the next page no matter what?

 

fixed issue, but if someone were to enter in the fields and press submit
it does nothing. they would have to refresh the page...?

 

The code you show has nothing to do with the next page. Where does the form direct to?

 

Yeah, this is kind of another case of "if we can't see the HTML the script is doing stuff to, we can't tell you what's wrong"

CSS without the HTML it's working on is gibberish... Javascript without the HTML it's working on is gibberish, etc, etc...
