Not found [CFN #0005] error
I have a DataAssist results page that submits form data to an eCart 'request for quote' page. I'm getting the error above, along with a blank page, on submit. Haven't found any info on web or in forums about this particular error. When testing on local server I get a different error:
'The requested URL /websitename.com/RequestforQuote.php1' was not found on this server.
Files attached with live link.
