Oracle Forms

Hi,

I'm trying to customize the menu and smart bar of my forms application, and I read in this forum that the demo file menudef.mmb and menudefs.mmb can be used for this purpose. I have downloaded the two files as part of the 10g forms demos (menudef_10g and menudefs_10g) and placed these files in my Oracle_Home\forms directory.
When I open these files, they come up as menus in the form builder object navigator.
However, when I set my form property 'Menu Module' to 'menudef' or 'menudefs', it gives me the error FRM-10221 Cannot read file menudef and doesn't display the menus.

Does anyone have an idea as to why this may be happening?

Thanks in advance,

Abigail
