When python executes the code to check if that specific value in the column is negative, I get an error: TypeError: 'int' object is not subscriptable.

That error means that you have an int variable, but you are using it as a list.

For example, if my program had a variable x = 5 and later I tried to use x[2], then that error would happen because x is an int and doesn't have subscripts like [2].

If may be that in your for loops, you have a variable that you thought was storing a row, (which would be a list), but it is actually storing an index value (which would be an int).
