I'm building a Qualtrics form that requires a respondent to enter their email address. That question is a single line text entry question type. The email address being typed correctly matters because I have display logic that relies on specific email addresses, and that display logic fails when emails are entered with a trailing space. I anticipate my respondents will use their phones to answer the survey, and phones are notorious for leaving trailing spaces in open text fields.

Normally, I would use the "Email Address" content type validation choice under "Response Requirements" to enforce only valid email addresses to eliminate the trailing space issue. The issue here is that I have custom validation already implemented on that question. It requires the text to contains our anization's specific email suffix. The question asks them to only enter email addresses with that suffix, but I don't trust people to read and follow directions, so I wanted it to throw an error if another email suffix was detected and force them to fix the error.

Current Conditional Validation Logic:

IF: Q2 Please enter your business email (@) 
>CONTAINS: "@" 
>THEN: Validation passes

I tried adding another logical statement to the conditional validation logic above that would reject validation if a space was contained in the response, but it did not work:

Attempted Conditional Validation Logic:

IF: Q2 Please enter your business email (@) 
>CONTAINS: "@" AND
>DOES NOT CONTAIN: " "
>THEN: Validation passes

Other ideas I had were:

• Changing the additional logical statement to match regex
• JavaScript that prohibits spaces in that question's responses
• Converting to a form field type question to enforce validation

For the first two, I'm not sure how to approach the creation of a regex or JavaScript that would meet my needs. Any thoughts are appreciated.
