SLK836,
As far as I know there is no Rank function (an incredible life saver in Excel!) in MS Access. However, what I have done is create a query. Then based on the results of that query, I create another query based on the same fields, and count how many records are above the current recordds based on the criteria of the current record.
For example, if you had a list of employees with their current salary, you would use the current record and count how many records in the current dataset have salaries greater than the current one. Then you add 1 (i.e. the highest salary will have zero records greater). This also accounts for ties, so that if record 3 and 4 are tied, they both receive 3's, but the next record is a 5.
Not sure if this makes sense, but without your data, and without writing your queries for you, this will get you in the right direction. I'll be glad to work through additioinal details....
