Access 2007 - Problems with saving on 1 form

Within my database, I have a bunch of forms, tables, queries, and reports.
About 2 weeks ago i added a button to "Form A" (for lack of a better name
within this question). The button prints 2 reports. There was no problem
saving the updates on this form and the button and form were working
perfectly. Since that change 2 weeks ago, i have changed and saved many
different tables, queries, reports, and other forms, none of which has a
problem. Now, I am trying to create a new button for Form A. However, after
making the button and adjustments, it will not allow me to save these new
changes. I closed out without saving and tried something as simple as moving
a text box and it still will not allow me to save the changes. If i try to
copy and paste this form so that maybe it will correct the problem (i am
trying anything at this point) it won't allow me to and pops up with "Name
Conflicts with existing module, project, or object library." Does anyone
have any ideas?
