can anyone help with this problem?

I have two linked worksheets one called 19Dec and the
other RW19Dec. RW19DEC has all calculations, while the
19Dec is the working user model containing the results of
calculations and macros etc.

Msg I am getting is

"Microsoft Excel cannot find 'macroname'on 'RW19DEC'.
There are two possible reasons

- the name you specified may not be defined
- the name you specified is defined as something other
than a rectanglar cell reference

check the name and try again."

What does this mean? The macros in question do not appear
in RW19DEC at all...

thanks for help

regards

Steve
