Greetings to all, Kindly help me in this ? Tried validating brings error

Welcome to the community, @hchoke! It seems like you are using the if-statement for ddCEREALS, a select_one question type, but your expression shows that you are trying to use it for a select_multiple question type.

For your reference, selected(${ddCEREALS},'yes' is used for a select_multiple question type while ${ddCEREALS}='yes' is used for a select_one question type.

I hope this helps you solve your issue.

Thank you @Kal_Lam for your response.
What is wrong with this coding for the following question;
if(selected(${ddCEREALS},‘yes’), . >0 and .<=7, if(selected(${ddCEREALS},‘no’) . >=0 and . <=6)

Question 1; Have you taken cereals and cereal products eaten in last 24 hrs

  1. yes
  2. no

Question 2: How many days have you eaten cereals and cereal productsin the last 7 days?

If Question 1 is yes, then the response to Question 2 should be >0 and <=7
If Question 1 is no, then the response to Question 2 should be >=0 and <=6

Will appreciate your input on this.
