Millisecond Forums

Hello,
In my script I have a 'on trial end' in my trials so I can display a score that changes. In this I have a 'value.scores' function. However, when I run the script I get an error for this function in only two trials. The other trails don't show an error, only two of them. Could someone help me figure out what is wrong with these two trials?

Here is what they look like, I will also attach the script as well.

Thank you so much for your help!!
