Use External Function

[Guest]

I want to use a function defined in one workbook within the VBA code of
another workbook.

My code looks like

b = 0
a = [personal.xls].UseIsOK(b)

but I get an error message

run time error 424

object required

The called function requires no arguments, but I get the same error message
if I use

a = [personal.xls].UseIsOK()
or
a = [personal.xls].UseIsOK

Any help would be appreciated.

Thanks.
