Update a var only after button click

[Larissa_Cury]

Hi. I’m redoing an experiment. In this version, user has to click on buttons (ranging from number 0 to 9), which will store their answer, and then this answer will be evaluated.
Ex: user clicks on ‘1″ and “5” and “9”, his answer is 159 (as a string)

I guess I was able to adapt the remaining parts of the old code, but I cannot make it store a variable ONLY IF a button is clicked. I cannot put “wait” on all buttons because user may skip some. I tried to change the buttons to a selector but I couldn’t as well. The idea is: user will have to click on the buttons based on a sequence of number’s they’ll hear and then I’ll check if their answer is right.

The post where Jeremy’s helped me with the logic is here: https://www.pcibex.net/forums/topic/get-the-previous-row-of-a-column/

I tried MANY things so far. I tried to add a .success to test.clicked() but it didn’t work.

Template("stimuliNew.csv", row =>
  newTrial("sequence-"+row.lenNumeric,
  newVar("lastLen",0).global()    // We'll set this to lenNumeric at the end of the experiment
  ,
  newVar("errorCount",0).global() // We'll update this after the key press
  ,
  // Create new variable 'answer'
  newVar("answer",'').global() 
  ,
  newButton("testA", "BUTTON 5!") // 5
  .print()
  ,
  getVar("answer").set(v=>v+'5') // 5
  ,
  newButton("testB", "BUTTON 9!") // 9
  .print()
  ,
  getVar("answer").set(v=>v+'9') // 9
  ,
  newButton("testc", "BUTTON 3!")  // 3
  .print()
  ,
  getVar("answer").set(v=>v+'3')  // 3
  ,
  newButton("testd", "BUTTON 6!")  // 6
  .print()
  ,
  getVar("answer").set(v=>v+'6') // 6
  ,
 newButton("testOK", "OK!")
 .print()
 .wait()
,
newText("printFirstKey", "")  /// just to see the variable
    .text( getVar("answer") ).print().center()
,
getVar("answer").test.is(row.keysBackClean)
 .success(
        newText("right","Correto! ✅").center().print()
        ,
        getVar("errorCount").set(0) // Correct: reset the value to 0
        ,
        getVar("answer").set(0) // Correct: reset the value to 0
        
        
    )
  .failure(
            newText("Incorrect").center().print()
            ,
            // Increment the value by 1, and check if it is equal to 2
            getVar("errorCount").set(v=>v+1).test.is(2).success(
                getVar("lastLen").test.is(row.lenNumeric)
                    .success(
                        newText("2 errors in a row for a sequence of the same length!").center().print()
                        ,
                        jump("end") // The next trial will be the one labeled "end"
                    )
                    .failure( getVar("errorCount").set(1) /* set to 1 if previous length was different */ )
            )
        )
    ,
    getVar("lastLen").set(row.lenNumeric)
    ,
    newTimer("wait-success",1000).start().wait()
)
);
