In one of my queries I need to look at logon / logoff times for staff for a given (variable) date range. The problem that I'm having is that if a person does not logon or logoff on the first / last day of the range (the data has to be grouped by day for other reasons), a null value is returned for this field.
Currently I'm just using the 'first' grouping on the totals line of the query - is there any way that I can tell Access to use the next (or previous)day in the range's data for this field if a null value is returned (a bit like previous or next could be used in Crystal Info)
Thanks in advance
