Blank Field in Form
I have a query that gets some criteria (City and State) from a form.
I have the State field set up as a ComboBox connected to a local table I created. If a user was to type in a City (i.e. "Springfield") and then leave the State field empty, then the query would have no results. How do I make the query so that if one of the fields on the form is left empty it will run for all possibilities (i.e. look for all Springfields in any state)? |

Blank Field in Form
Assuming the name of your form is FrmCityState and there are two textboxes
named City and State on the form, put the following expression in the criteria of the City field in your query: Forms!FrmCityState!City Or (Forms!FrmCityState!City IsNull) and put the following expression in the criteria of the State field in your query Forms!FrmCityState!State Or (Forms!FrmCityState!State IsNull) Steve "Bvdman32" wrote in message ...
