In the past few weeks I have made a start on a guide for Photoshop to teach non technical users how to use certain tools. I also organised my work as it was not in the correct folders, but I am still not sure if it is all in the correct place. For Unit19 I got non technical users to test my spread sheet to see if it works correctly and for them to identify any faults or errors that occur. A problem that occurred was that a page was not protected so they could edit the information therefore changing all of the values within the charts. With these problems noticed I fixed them and kept evidence of me doing so.
