When I run check logic on my survey I get the following error on one question.
Each question has one sub-question - "Please select your response", and 11 Answer options.

The question code in this error message is ACTV1:


(VALIDATION: ((if(is_empty(1), 1, count(ACTV1_SQ001.NAOK) <= (1))))


(Tip: if( ! is_empty('') && is_empty(1) && ('') != 1, sprintf('Please select at least %s answers', fixnum('')), '')
if( ! is_empty('') && is_empty(1) && ('') == 1, sprintf('Please select at least one answer', fixnum('')), '')
if(is_empty('') && ! is_empty(1) && (1) != 1, sprintf('Please select at most %s answers', fixnum(1)), '')
if(is_empty('') && ! is_empty(1) && (1) == 1, sprintf('Please select at most one answer', fixnum(1)), '')
if( ! is_empty('') && ! is_empty(1) && ('') == (1) && ('') == 1, 'Please select one answer', '')
if( ! is_empty('') && ! is_empty(1) && ('') == (1) && ('') != 1, sprintf('Please select %s answers', fixnum('')), '')
if( ! is_empty('') && ! is_empty(1) && ('') != (1), sprintf('Please select from %s to %s answers.', fixnum(''), fixnum(1)), '') )

SQ-1 ACTV1_SQ001 Please select your response

NOTE: All the questions are set up the same, but the error only comes up for one question each time.

If I delete the question that had the error and re-create it, Check Logic brings up the same error for a different question that had no error the previous time Check Logic was run.
The error is always for one question only, even though they are all configured the same.

How can I address this issue?

Why are you using an IF statements in the question validation equation.

Wouldn't an OR work?

That's just it, I didn't do any custom coding. I used the GUI. So, I don't know why the errors are popping up.
I didn't enter the code. Any idea why I'm getting code related errors?

Thanks in advance
