I am trying to track who iputs data, who changes it and when. I have all the fields needed in the tables. I have the forms with the fields in them. I want the information to auto populate. I know I can do this on every single form, but I thought it would make more sense to create a module with a function that could fill in the text boxes with the appropriate user name and date, and if someone tries to change that info it pops a message that says hey you cant do that, and changes it back.

I would appreciate any help,
