I have a survey question (S9) which has 7 response options. It is a check box question for multiple responses.
I am trying to create skip logic so that if only response 7 is selected the respondent is disqualified.
I tried using this which does not work
S9_7=1 and (S9_1=0 and S9_2=0 and S9_3=0 and S9_4 and S9_5=0 and S9_6=0)
The error message says "The binary operator 'and' requires boolean expressions on both the left and right side"
How do I make the skip logic so that if the respondent ticks the box for S7 only that they are disqualified?
