I was wondering if its possible for me to have a button that will take some data and inserted it in a pre made form which is .pdf, like an application. this will prevent me from copying everything over into the form by hand. Help would be appreciate it.

Macros aren't going to do this for you. You could use VBA to populate an access form and print the form. Or use VBA to populate a Word or Excel form, but I'm not aware of any way to populate a PDF file.
