Resolved I get an error when running compiled script in VS code, runs otherwise in psychopy

I’m running ito this:

I’ve tried a lot of things and I couldn’t get it to work. I’ve made many changes inside the builder but nothing has worked. Here’s my code and the error informaiton:

Exception has occurred: TypeError
'TextStim' object is not iterable
  File "C:\Users\mw24396\Documents\GitHub\DANVA\2_template demographics inside psychopy builder.py", line 388, in <module>
    iter(next_button)

which is happening when I run this code:

#!/usr/bin/env python
