I have this query that adds up the total mileage of our trucks. The query runs fine when I only pull information for about 20 days. Now when I try to pull information for lets say a 3 month period it will not run and gives me an error message saying "data type mismatch". Basically, I was wondering if there are any number limitations that access have that is preventing me from pulling all the mileage over a long period of time.
