Okie...sheesh...after a while I figured it out

...after crashing my office twice
First save your template to something else test.xls
then unprotect your sheet by going to --> tools\protection\unprotect sheet
Once thats done highlight your figures --> right click on them --> choose format cells
this is the original formula
_("$"* #,##0.00_);_("$"* (#,##0.00);_("$"* "-"??_);_(@_)
change it too
_("£"* #,##0.00_);_("£"* (#,##0.00);_("£"* "-"??_);_(@_)
this should change your $ to £...hopes this helps....

- then save the the excel sheet as a template so you don't have to create it again...remember to protect the sheet before you save it as a template
Don't ask me how to create the forumla/macro, as I don't have a clue, I can hack Office to suit me needs ....heheheh ;p
