Hi -
The issue is that forms with code in the Sandbox (published directly to the library) cannot have email submit connections. Here's a link with more info on this.
If you aren't able to admin approve your form, and this means you need to take a different direction, please contact [email protected] about a refund for your qRules purchase. Please reference this thread in the email.
If the form has be published directly to the form library and has to have email submit connections, it won't be able to also have code, whether qRules or custom code.
