I am sure it's in the documentation somewhere, so can someone point me in the right direction?
I would like to check for typos in email addresses by asking the use to repeat typing their email address.
I would get two addresses, check if they were the same and flag up an error if not.
Any ideas?

Hello,

Hopefully I have understood your need.

Admittedly, I have made some 'assumptions' - your user has provided their email address to register on your website, your user is logged-in in order to use / submit the form.

What I have done, and this might not meet your needs . . .

Under the 'General' tab for the email field - in the 'Default Value' text field put in: {global:useremail}

This should retrieve their registered email address and place that email address in the email text field when the form is viewed on the front-end when logged in (i.e it pre-populates the field).

Now, going to the 'Attributes' tab - for the form email field, scroll to 'Additional Attributes', in the text field (for 'Additional Attributes') type in: readOnly="readonly"

This 'Additional Attributes' readOnly instruction to RSForm (pro) does NOT allow editing of the email address in the form - so user typo each time they use the form is potentially reduced. It will only allow the email address to be read (not edited).

So, the user email address will be the one from their profile - without them having to type it whenever they use the form - it gets pre-populated and cannot be edited in the form at the site's front-end.

Hope this goes at least a little way to meet your need. If not, perhaps come back and post a reply - between us we may find the answer you need.

If you need greater clarification of what I say here - please reply in this thread / topic.

Regards,

Tim A

If you simply want to check by comparing create two email fields and under validations set the second to 'same as the first' and put the first field in 'field name to compare with'
