Response of 'error' each time I submit my code below

Screen Link:

My Code:

fb_rating_data = [row_1[0], row_1[3], row_1[-1]]
insta_rating_data = [row_2[0], row_2[3], row_2[4]] 
pandora_rating_data = [row_5[0], row_5[3], row_5[4]]                   

avg_rating = 
(fb_data_rating[2] + insta_rating_data[2] + pandora_rating_data[2]) / 3

What I expected to happen:

What actually happened:

Running your code caused an error.
fb_rating_data isn’t defined in your code, but we expected it to be list type
insta_rating_data isn’t defined in your code, but we expected it to be list type
pandora_rating_data isn’t defined in your code, but we expected it to be list type
avg_rating isn’t defined in your code, but we expected it to be float type

The above is my answer to the question asked on that page and it tallies exactly with the answer given for it. But each time I submit it brings up “error” above. It’s almost a week now. Pls kindly help me look at it.

The underlined variable names are not the same.
