I am having trouble figuring out how to implement something which I thought would be relatively easy. Basically, I am having participants take a survey and am tracking their eye movements using the tobii plug in. Since there are multiple survey pages, I would like to know the survey page that corresponds to the eye tracking data. As you can see from the code below, I have tried to implements 'markers', but it hasn't worked. Could anyone offer any insight?

<surveypage TS_AVC_1_A>
/ questions = [1 = Intentionality_AV_1]
/ showpagenumbers = false
/ showquestionnumbers = false
/ branch = [surveypage.TS_AVC_1_B]
/ recorddata = true
/ datastreams = eyetracker
/ screencapture = true
/ ontrialbegin = [
values.marker = "1";
]
/ stimulustimes = [0 = Marker]
</surveypage>

<surveypage TS_AVC_1_B>
/ questions = [1= Anger_instr_AV_1, Anger_AV_1, Irritability_AV_1]
/ showpagenumbers = false
/ showquestionnumbers = false
/ branch = [surveypage.TS_AVC_1_C]
/ recorddata = true
/ datastreams = eyetracker
/ screencapture = true
/ ontrialbegin = [
values.marker = "2";
]
/ stimulustimes = [0 = Marker]
</surveypage>
