hello, any idea where this typeerror could be coming from? the columns being combined im the df are all of the same type, so im not sure what the issue is. would appreciate any help!

Task 5: Write a process_transactions function that modifies a transactions DataFrame and appends it to the positions DataFrame (as in Tasks 2-4) Be sure you: 1. Make quantity negative for sells 2.
