Hi All, I'm new to the Qualtrics API and trying to figure out the basics right now. I've used two previous posts to try and figure this out listed below:
https://www.qualtrics.com/community/discussion/579/javascript-basics - for function on accessing previous answers
https://www.qualtrics.com/community/discussion/2640/javascript-code-for-show-and-hide-information- for jQuery hide function

I can't seem to get anything to work and when I look up the Qualtrics API library it doesn't really help me understand how to use the functions. This is the code I've tried:

Qualtrics.SurveyEngine.addOnReady(function()
{

if ("${q://QID3/ChoiceGroup/SelectedChoices}" == "${q://QID9/ChoiceGroup/SelectedChoices}")
{ jQuery("#QID11").hide();}


}
I'm comparing questions 3 and 9, which are singular slide scales from 0-10 and then trying to hide 11 if they answer 3 and 9 the same way.

If QID3 and QID9 are single sliders, then your pipes are wrong. It should be:
```
Qualtrics.SurveyEngine.addOnReady(function() {
if("${q://QID3/ChoiceNumericEntryValue/1}" == "${q://QID9/ChoiceNumericEntryValue/1}") {
jQuery("#"+this.questionId).hide();
}
});
```
You should always pipe the value into your Question Text using "Piped Text..." then cut and paste it into your JavaScript.
