Hi Andy,
I just tired it on my lapdog adn it seem to work fine that is
http://lemans.tmdg.co.uk/Call.xls First on Balances sheet.
You need to change the names in B2 though Z2.
Enter the Exchange rate in B5 though Z5.
Enter the number of shares for each person in B6 though Z6
Then on the Outgoings sheet.
You should be able to clear all of the values in the Amount Column that should zero all the numbers on the Balances sheet.
If you are running out of rows on Outgoings just copy a blank line.
Finally you columns A B C and D for each item spent. The Balances should happen Automagically.
Tom.
