Thank you
Yes the subform is based on a query. At the moment I have two combo boxes. With one you choose the "tool" with the other the "tool size". Once trhe two selections are made the subform shows the data filtered by "tool" and "tool size".
I whish, if possible to have only one combo with two column Column 1 "tool" Column 2 "tool size".
toolA size1
toolA size 2
toolB size 1
toolB size2
When you choose one the subform should appear with data filetered by tool and size, without going through two choices.
About the ordering I am not sure, data are ordered by tool and tool size I guess
I hope this is clear
Thank you again
