Dates In Queries

I have set up a query to add up some data. I used the wizard to set it up, I set the fields I wanted added, then it asked how I wanted my dates handled and I selected by Month. All of this works fine, but when I very the results in datasheet view, the months are not sorted properly. I went into design view and selected to sort by the needed column, but still no luck. The problem is that the month/year is being sorted alphabetically instead of chronologically. Is there any way to fix this, I am looking around in what I have for an answer but can't seem to find anything.

Thank you for your assistance.
