Load XLB File with worksheet?

[L.A.]

I've set-up a customized menu and other options for a worksheet that
functions as a form. I was able to save the XLB file with the customizations.
How do I start the worksheet with the XLB file from a shortcut?

I've tried a string like, P:\TESApps\CI\Estim1.xlb
P:\TESApps\CI\estimatesCI1a.xls as the target in the shortcut but was only
able to start Excel with the XLB file with no worksheet loaded.Is there a way
to do this?

THanks for your help
