Youtube Tutorial Stroop Task Pasrt 2

PsychoPy version (e.g. 1.84.x): 2023.2.3
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?:

I am trying to complete Part 2 of the Stroop task youtube tutorial. However, when I get to a certain part I keep getting the same error:

File “/Users/dm/Documents/Experimental Programmes/Stroop 2/Test_lastrun.py”, line 421, in run
word_list.append(word)
UnboundLocalError: local variable ‘word’ referenced before assignment
################ Experiment ended with exit code 1 [pid:20394] #################

What did you try to make it work?:

I have tried referencing word as a string in the begging section of the code, however, the same issue comes up for ‘colour’ which again I repeat myself and then issues come up for the RGB.

Thanks for any help

Do you have a text component which displayed $word?

It needs to be set to update each repeat and not be constant (set once at the start of the experiment)

Thank you for replying.

I do have $word, however, it is already set to set every repeat.

Does $word appear in any code components? I assume that the routine that references it is inside the loop that points to the spreadsheet.

Word appears in the StroopTrial Component.

curr_item += 1

word = word_list[curr_item]
colour = colour_list[curr_item]

correct_key = colour[0]

Is the code component above the text component or below? It should be above if the code is in Begin Routine.

The code component was below the text, however, I have moved it to the top, yet I am still getting the same error.
