Peter,
[Medium 1] is the field name of the table. I am trying to ask the query to show all records if the combo box on my form is empty. Your formula worked, except it only worked if I used it on one column of the query (one field of the table). I am trying to filter on 5 different fields of the table. I have 5 combo boxes on a form to fill in with options to filter on. However, if they only want to fill in one box, I want the query to filter on that one, and show all records for all the other fields. The problem I run into, is that it will do what I want, as long as there isn't a null value in the record. If there is a null value in any of the other 4 feilds within the table, it won't show those records in the query.
I hope I explained this well enough. I put an example below that we can all relate to. I am not familiar enough with SQL to write the equation there. I would like to write the equation on query criteria if possible, but if not, please indicate where I need to start.
Below is an example of what I am trying to do:
Table of cars
Make:
Model:
Year:
Color:
Horse Power:
I want to be able to filter on any of these 5 fields in the table using combo boxes on a form. However, if I only fill in the Combo box for "Make" on my form that is linked to the query with "Ford", I want it to show me all the "Ford" cars in the table. However, if the color or horse power are left blank because they are not required, I still want to have the query show me all the "Ford" cars and just show blanks for the color and horsepower. If I want a "Ford" that is an "F-150" that is "Black", I would like it to show me all the records for those three criteria.
Thanks for all your help,
Curtis
