I use Access 2010.
I have a combobox [Filter_Location] on a form [frm_Planting] and I want to use the value of the combobox in a query criteria. If the combobox is empty, I want all the values in the source. Otherwise I want only the values specified by the combobox.
I use the following criterium, but the problem is if the value of the combobox is 3, the query also give me values for 13, 23 etc.
Like "*" & [Forms]![frm_Planting]![Filter_Location]
