thebane, I don't have that problem. What cell does 'Err:511' display in? Also, which version of OpenOffice are you using? 3.0?
Yarthok, thanks.
I currently have Open Office 2.4 Woops!
And the error occurs on the 'Attacks' page 'E20'.
If I select Short Bow or Long Bow in the Weapon / Implement Type, the above field comes up as err: 511.
