hello, just downloaded (paid version) this form stack from @willwood RWExtras and used on my test-site. First the stack won’t work on a stacks page if there are other similar stacks around (doobox Contact Form, stacks4stacks Formulate) but after putting the Compact From stack on a new stacks page it was visible on the published page.
Now while testing the page I get an error notice after clicking the send button:
Notice: Undefined variable: error in /srv/www/vhosts/uhebeisen.ch/subdomains/wal/httpdocs/sport/rwe-kontakt/files/stacks_page_page15.php on line 39
This message is displayed in the browser window instead of showing a success message on the webpage the form is placed. How can I fix this?
ps the test-site is running here.
