Word2000 transfer userform into template

Hello all:
I am grateful for your help. Please help me with the following:
I have a template with a table. The table has three possible choices for users to choose from. Each choice is a command button.
I want to insert Userform1 into the form if the commandbutton1 is pressed, or Insert User form 2 if command button 2 is pressed or insert userform 3 if command button 3 is pressed. When I insert the appropriate userform, I want to delete the table of choices and insert the form where the table of choices was in the active document. Can you please help?
