Hello,

In my experiment, participants will hear a sound clip with a scream and in the middle of the scream, there will be a control question where a number is played. After the scream trial, participants will be asked a control question and they have to enter the number they heard. At the same time, I will be keeping a tally of the number of coins participants have left. When participants get the number incorrect, I would like them to get notified that they will lose two coins, and I would like their "coins_left" value to subtract two. Is this possible? 

Below is my relevant code

<sound scream1>
/ items = ("one_new.mp3")
/ select = replace
/ erase = false
/ volume = 0
</sound>

<sound scream2>
/ items = ("two_new.mp3")
/ select = replace
/ erase = false
/ volume = 0

/ items = ("three_new.mp3")
/ select = replace
/ erase = false
/ volume = 0
</sound>

It's possible in exactly the same way you already subtract coins in the betting trials. The code you provided, however, is not in the least bit functional. <textbox> elements are neither trials not blocks. They belong on surveypages (surveypages are trials), and those pages belong in a block.

It's possible in exactly the same way you already subtract coins in the betting trials. The code you provided, however, is not in the least bit functional. <textbox> elements are neither trials not blocks. They belong on surveypages (surveypages are trials), and those pages belong in a block.

Thanks Dave, yes I do have surveypages sorry! An example surveypage is the following:

<surveypage controlQ1>
/ questions = [
    1=controlQ1]
/ showpagenumbers = false
/ showquestionnumbers=false
</surveypage>

Could you give an example of how the line of code would look to subtract 2 coins for an incorrect response? I'm just not sure what specifically to change from the line of code for the betting coins values. 

The coding line for the betting was
/ ontrialend = [
    values.coins_left-=radiobuttons.bet_radiobuttons.response;
]
