Group: Forum Members Posts: 37, Visits: 165	Hello! We will receive participants from several different participant pools, so we need to redirect them to different sites afterwards to give them credit. However, our logs show that everyone is being redirected to the same page: Prolific, with a custom completion code added to the end (i.e., not "INITIALIZED" like in the code). Could you show us how we can ensure that the script can dynamically and safely set the finish page? We already confirmed that "parameters.finishpagetype" is being set correctly. Full Experiment <defaults> / minimumversion = "6.0.0.0" / finishpage = "https://app.prolific.co/submissions/complete?cc=INITIALIZED" </defaults> <batch fullexperiment> / file = "infopage.iqx" / file = "DelayAAT.iqx" / file = "debriefing.iqx" / onscriptend = [ // set language if(batch.fullexperiment.currentscript=="infopage.iqx"){ parameters.finishpagetype=values.finishpagetype; } ////////////////////// // Completion codes // ////////////////////// if(parameters.finishpagetype=="Prolific"){ defaults.finishpage = "https://app.prolific.co/submissions/complete?cc=<%parameters.completioncode%>"; } if(parameters.finishpagetype == "SalzburgUni"){ defaults.finishpage = "https://XXXXX.sona-systems.com/webstudy_credit.aspx?experiment_id=XXXXX&credit_token=<%parameters.completioncode%>&survey_code=<%script.groupid%>"; } if(parameters.finishpagetype=="Other"){ if(values.completioncode == values.correctcc){ defaults.finishpage="https://XXXXX?lang=en"; }else{ defaults.finishpage="https://google.com/"; } } ] </batch> ############## # completion # <values> / correctcc = "XXXXX" / screenoutcc = "XXXXX" / rejectcc = "XXXXX" / finishpagetype = 0 </values> <parameters fullexperiment> / completioncode = "INCOMPLETE" / finishpagetype = "indeterminate" </parameters>

Otherwise the web setting will override whatever you set in script.

Group: Forum Members Posts: 37, Visits: 165	Unfortunately the issue persists. The issue seems to be that the /onscriptend bit in the batch script does not always run. I now set a parameter in the following manner: parameters.debug="I have run."; And I've added a script debug.iqx that comes after the first script, with the following code: <text debug> / items= ("<%parameters.debug%> is the debug value") / position = (50%, 95%) / size = (100%,10%) / valign = center / halign = center / vjustify = center / erase = false / txbgcolor = transparent / fontstyle = ("Arial", 2%, false, false, false, false, 5, 1) </text> <trial debug> / stimulustimes = [0=debug] / validresponse = (anyresponse) </trial> <parameters> / debug = 0 </parameters> Most of the time this just gives me 0 even though I set the debug parameter in the batch script. What do you advise?

What do you advise? Then you're not actually setting the parameter.

Group: Forum Members Posts: 37, Visits: 165	Some more testing reveals that the / onscriptend bit is aborted once it evaluates if(parameters.finishpagetype=="Other") as true It does not run what's between the {} and it also does not run anything after that, including code that is not enclosed in {} brackets anymore, including the aforementioned setting of a debug variable.

Then you have syntax mistakes. You don't show the actual code, so there's no way for me to tell you where you're going wrong

Group: Forum Members Posts: 37, Visits: 165	If parameters.finishpagetype is set to anything else, then no such aborting occurs and the debug parameter at the end is set.

Again, whithout you showing the actual code you're talking about, there is no way for anybody to spot and point out where your syntax mistakes are.

Group: Forum Members Posts: 37, Visits: 165	It appears the issue was caused by my use of values.completioncode, which was not set anywhere in <values>; it was supposed to be parameters.completioncode. My use of values.completioncode in that if-statement caused the code to quit working from there and onward, without warning.
