Is your survey entering the branch "Choice is equal to Accept".
I dont see any value set to embedded data "Choice" in the survey flow.
Is it set somewhere thru java script in the block "Intervention_2"

Where are you setting the values of WTP_Random and WTP_Subject? In WTP_1 JavaScript? If so, post your script.

Hi, “Choice” is set in intervention2 and that seems to work.

WTP_Random and WTP_Subject are set in WTP_1, please find the code below:
Qualtrics.SurveyEngine.addOnload(function()
{
/*Place your JavaScript here to run when the page loads*/
 
});
 
Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
 
});
 
Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/
 
});
 
Qualtrics.SurveyEngine.addOnPageSubmit(function(type)
{
if(type == "next")
{
Qualtrics.SurveyEngine.setEmbeddedData("WTP_Random",(Math.random() * (0.21 - 0.0) + 0.0).toFixed(2));
Qualtrics.SurveyEngine.setEmbeddedData("WTP_Subject", jQuery("#"+this.questionId+" .ResultsInput:eq(0)").val());
console.log("${e://Field/WTP_Random}");
console.log("${e://Field/WTP_Subject}");
 
 
}
});

Your WTP_Subject jQuery syntax is wrong. It should be:
Qualtrics.SurveyEngine.setEmbeddedData("WTP_Subject", jQuery("#"+this.questionId+" .ResultsInput").eq(0).val());

Hi Tom,
Thanks for your reply - unfortunately the logic still doesn't work. I've attached a .qsf of a dummy trial below - the full experiment is much larger and made up of multiples of these trials.
Many thanks, Chris

In branch logic, we pipe the text in the last text box:

Thanks Rondev, this seems to be working now!
