Filter a Form by Switchboard Item

[ranen]

I am using a switchboard in my database, I have 3 forms using the same query,formats,etc but the 2 of 3 have filters. My question is how can I filter the form when I click a button in the Switchboard.

I tried to do
docmd.applyfilter
but when the form is open nothing happens.

And I also use the Form_Switchboard!Itemnumber = 2 but the only number it can see is with 0 value.

Please help me. I just don't know how to catch the field from Switchboard. Please help. Thank you so much.
