I've got a baseball team and I'd like to create an app where each player can select their number and then select from a number of drop downs to rate themselves on different game skills(Low/Med/High). Once completed, the data is time stamped and saved. I do not want the player to be able to see other player ratings when finished, but seeing his own entries is okay. The end goal here is to have this player list with each of the skills list populated with what the player entered and ready for analyzing to see who should be promoted to the next league. (There will be a part B where the coach will be able to enter in data for each of his players, but really, baby steps.)
I stopped when I kept running into challenges with the Find Replace tool...

I'm at a loss here. Is this even possible? Sample data below. I entered in the "Unknown" as a place holder thinking I'd use Find Replace, but I'm not having luck with that. Can basically pull out the player and add the time stamp, but entering and saving the skills I'm at a loss...
