Excel Macro's extended to a worksheet on ppt slide

[VBA_Newb]

Hello,

I've written some VBA code and added it to my personal.xlsb file - which
everything works great in excel. However, when I insert an Excel
Macro-Enabled Worksheet into a PPT slide the macro's are not available to
that embedded worksheet. This has worked in the past, but for some reason it
stopped working. Any suggestions would be helpful.

Thanks!
