Update Hidden Value If Question Answers Do Not Match

We have a feature that will verify two textbox questions on the same page match (Example: Verify that the respondent enters the same email address twice). 

This code snippet is used to check to see if the answers to any two questions in the survey match. If the answers to these questions match, a hidden value is populated with "match".  If the answers to these questions do not match, a hidden value is populated with "flag".

Add a Custom Script action and copy and paste the following code. Make sure the action follows the question from which the Hidden Value pulls. The hidden value can be anywhere in the survey in relation to the script, even the same page!

This scripting option uses the following features:

• Hidden Value Action
• Custom Script Action

Setup

1. Start by building the survey and adding the duplicate questions.

We recommend creating one question, saving, and copying the question to ensure that the reporting values in both question are identical. You can move the second copied question to a later survey page.

2. Add a Hidden Value Action. We recommend adding this to the very top of Page 1, or the first page in your survey, so it is easy to identify when you are reviewing responses. 

You will not prepopulate the Hidden Value here, simply name the Hidden Value and save.

3. On the Thank You page of the survey, or on the survey page after the copied question from Setup #1, add a Custom Script Action.

Copy and paste this code into the action.

//compare two questions; if not same value, set a flag in hidden value

%%q1 = sgapiGetValue(6); //change this to the ID of your first question
%%q2 = sgapiGetValue(7); //change this to the ID of your second question

if (%%q1 != %%q2) {
  sgapiSetValue(5,"flag");
}
else {
  sgapiSetValue(5,"match");
}

4. Update the IDs and Hidden Value flags.

%%q1 - ID of the first question

%%q2 - ID of the second copied question

Hidden Value ID - in the example code above our ID is 5.

Update the text to populate in the Hidden Value field if necessary. In our example above, the Hidden Value will be populated with match if the question answers match and flag if the answers to the questions are different.

Save Custom Script Action. Test. Enjoy
