Toolbar buttons are gone
 

I have created a worksheet for tracking some information and I created a
custom toolbar with 2 buttons on it. One button is just a macro for sorting
the data and the other brings up a userform I made in VBA where you enter
info about clients and it adds it to the worksheet. My problem is that when I
put the worksheet on another computer the tool bar is there and the macro and
userform code is there but the buttons are gone. How can I make these stay?
The toolbar is attached to the worksheet and the macro and userform are still
there. Any help would be appreciated. Thanks
