Use Custom Validation on the second slider. The slider value must be less than or equal to the piped value of the first slider.

Thanks ​@TomG.  I used this logic (see pic). During preview the error message I created displays and wont let me progress, even if a value is selected less than the first slider.  I note that when I programmed the custom validation, no options populated in the drop down box for conditions. Do I need to create an embedded field or hidden captured text for the custom logic to work?

I’m assuming you labeled your slider “1”.  The condition should look something like:

Q10.27.2 … 1 Is Less Than or Equal to ${q://QIDxx/ChoiceNumericEntryValue/1}

Where QIDxx is the QID of the first slider

Thanks ​@TomG.  I’m not sure what’s going on, however using this logic continues to trigger my  error message and won’t let me proceed with the next question even if the value is lower. I wonder if the issue was that I had altered the QID’s or was using numbers with decimal points. But when I duplicated the questions and used the Qualtrics-assigned question numbers in the same logic, the problem persisted. Inverting the operation and setting the condition that Slider 1 is > or equal to Slider 2 didn’t resolve the issue. 

It could be that the pipe for the first slider doesn’t end in /1. Pipe the slider 1 value into your Question text, then copy the piped string into your validation condition.

Hooray ​@TomG 

The issue was a hidden QID, revealed by piping text.

Thank you!
