Hi Jeremy,

That’s perfect, thank you! I have yet another question. I want to have a score tracker and for that I initialize a global variable with newVar(“value”, 0).global(). But when I try to update a Text element with getText(“value”).text( getVar(“value”) ), I get an error message I cannot decipher. The code and the error message are below:

newTrial("Begin_2",
   
    newVar("value", 0).global(),

    newText("<h4>You are about to start Phase 2!</h4>").print(),

    newButton("Begin Phase 2!")
        .center()
        .print()
        .wait()

);

Template( GetTable( "icon.csv" ), row => 
    newTrial("Phase_2",

        newCanvas("score", 600,20)
            .add( 275, 0,
                newText("score", "score: ")
            ).print()
            .add( 325, 0,
                newText( "value", "0" )
            ).print()
        ,
        
        getText("value").text( getVar("value") ),

); 

And the error message:

[8:33:40] Command ‘0’ unknown on Var element ‘value’. (PennController: 34)
[8:33:40] Command ‘length’ unknown on Var element ‘value’. (PennController: 34)
[8:33:40] Command ‘parentNode’ unknown on Var element ‘value’. (PennController: 34)

Thanks,
