ReferenceError: Can't find variable: None

I tried replicating a previous experiment on my builder and experienced this reference error “ReferenceError: Can’t find variable: None” even though i did not call on the variable None anywhere in my experiment. I am new to coding and am very confused as to why this issue is occurring as I did not call on this variable throughout my experiment.

Any help would be great!!

Hello carmel01

you could find which variable is causing the problem by adding

print("yourVarname: ", yourVarname)

in the relevant code-component(s). This will print the values of your variables to StdOut. This should help you to find the variable causing the problem.
