I have a Table or query that I want to use a group filter. I have a good example from an access book but whenever I try it I get the error "Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another" Then "Can't filter records. The field name specified in the GroupFilterField property must contain values that have the same or a compatiable data type as the values in the group filter control".
I have looked at this every way I know how. I have an exact example from some code in an access book and even a sample dbase that works like I want this to work. I just can't seem to get past this error.
