Ok I know, may be it's easy but i just can't figure out how to do this
I have a form, on which there is a control (eg. Combobox1) in which I chose one topic (eg. Month number)
In the query I make a reference on this combobox
Forms![Combobox1]
It's Ok when I work with one topic but if I can't to select all of them.
The idea of Iif(Forms![Combobox1]=all;'*';Forms![Combobox1]) doesn't work.
I don't want to make another query for the case of "all topics".
Please help, I already get nuts about it. Thanks anyway.
