>Does anyone know how to test for the existence of a object?

Just a little reasoning behind some answers you got. VarType() was added after Type(). Type could return an 'O' for a variable even though its a destoryed object and is now NULL, thats why when using Type(), follow with an IsNull(). Where VarType() alwasy returns an 'X' for a NULL variable.
