Millisecond Forums

Taking the script in the thread you mentioned as a basis, you can (1) set an exceptionally high number of repeats that no one will ever realistically exhaust, and (2) track the number of attempts per page via a bunch of values.

<values>
/ pg1_attempts = 0
/ pg2_attempts = 0
/ pg3_attempts = 0
</values>

<block myblock>
/ trials = [1-1000=sequence(pg1,pg2,pg3)]
</block>

<surveypage pg1>
/ ontrialend = [values.pg1_attempts+=1]
/ caption = "Page 1"
/ questions = [1=rb1]
/ skip = [radiobuttons.rb1.response=="A" || radiobuttons.rb1.response=="B" || radiobuttons.rb1.response=="C"]
</surveypage>

<surveypage pg2>
/ ontrialend = [values.pg2_attempts+=1]
/ caption = "Page 2"
/ questions = [1=rb2]
/ skip = [radiobuttons.rb2.response=="A" || radiobuttons.rb2.response=="B" || radiobuttons.rb2.response=="C"]
</surveypage>

<surveypage pg3>
/ ontrialend = [values.pg3_attempts+=1]
/ caption = "Page 3"
/ questions = [1=rb3]
/ skip = [radiobuttons.rb3.response=="A" || radiobuttons.rb3.response=="B" || radiobuttons.rb3.response=="C"]
</surveypage>

<radiobuttons rb1>
/ options = ("A", "B", "C", "Skip")
</radiobuttons>

<radiobuttons rb2>
/ options = ("A", "B", "C", "Skip")
</radiobuttons>

<radiobuttons rb3>
/ options = ("A", "B", "C", "Skip")
</radiobuttons>
