I am trying to complete the statement of cash flows for a comprehensive problem

I am trying to complete the statement of cash flows for a comprehensive problem in Intermediate Acct III and cannot get the right total for Cash flow used by operating activities. Which accounts do I refer to when completing this statement and which accounts will need to be adjusted before entering on the SOCF? Any information regarding this particular statement would be greatly appreciated. I have the rest of the assignment finished but cannot get the cash flows correct. (I have been trying to upload my file along with this question for an hour and it still says 0 files attached. Is there another way I can get the file uploaded?)
