Close statement not working

If anyone has any experience with VBA you could help me out greatly.
Here's the way it goes, i have 3 forms.  in each form is an if statement that jumps up to the next form in a certain hierachry.  Form1 is the first form loaded, then Form2 and then Form3.  So, once these forms have been opened, i need to be able to close them and continue code execution on the previous form.
'form1 stuff
Commandbutton_click
     form2.show
     'stuff that needs to be exectued after form2 is done running
end sub

'form2 stuff
commandbutton_click
     form3.show
     'stuff that needs to be executed after form3 is done running
     close
end sub

'form3 stuff
commandbutton_click
     'stuff that form3 runs
close
end sub

the problem is that the Close statement is not closing the form like it's, seemingly, supposed to.  if i do an End statement, all of the forms close and no further code exectution takes place.  how do i get the forms to close themselves when the buttons are clicked?! i can't figure it out.  thanks
