Branching problem

Hi All,

I have been trying to get my program to go from video > survey page > waiting page, in this consecutive order. I thought I inputted the correct lines; however whenever I test it, the program skips the survey page. Any help would be appreciated!

<surveypage PRAC_Q>
/ questions = [1=PRAC_Q]
/ nextbuttonposition = (40%,70%)
/ finishlabel = "Click to procced"
/ showquestionnumbers = false
/ showpagenumbers = false
/ showbackbutton = false
</surveypage>

<caption PRAC_Q>
/ caption = "Please describe what you saw in the movie for the next 60 seconds.~r~r
Please keep talking for the entire time. When you are ready, click the button to proceed to start the timer."
/ position = (50%,50%)
/ fontstyle = ("Arial", 2.5%, true)
/ size = (50%, 45%)
/ txcolor = white
</caption>

<trial Wait>
/ ontrialbegin = [clock.timer.start(0)]
/ stimulusframes = [1=wait,timer]
/ validresponse = ("t")
/ inputdevice = keyboard
/ responseinterrupt = immediate
/ trialduration = 10000
/ pretrialpause = 250
/ posttrialpause = 250
</trial>

<trial PRAC_GD>
/ stimulustimes = [0=PRAC_GD]
/ responseinterrupt = false
/ timeout = 45000
/ branch = [surveypage.prac_q; trial.wait]
/ pretrialpause = 250
/ posttrialpause = 250
/ validresponse = (57)
/ inputdevice = keyboard
</trial>

<block PRACTICE>
/ trials = [1-3=noreplace(PRAC_GD, PRAC_TOM, PRAC_RD);4=taskstart]
</block>

Thank you!

This is wrong. You cannot /branch to two different elements *at the same time*. From the "video" <trial>, you need to /branch to the <surveypage>. From the <surveypage>, you need to /branch to the "wait" trial.

<trial PRAC_GD>
...
/ branch = [surveypage.prac_q]
...
</trial>

<surveypage PRAC_Q>
...
/ branch = [trial.wait]
...
</surveypage>
