ODBC Command parameters

I am using VS2005. I have went through the Command Wizard to set up a ODBC Command with my custom query. I am not sure how to setup the query so that it gets the parameter from a combobox to insert into my query.

When I am in the Database Expert dialog box and I right-click on the Command and select "edit command". It brings up the dialog box to edit my query statement and create parameters. This is where I am stuck. How do I get it to grab the parameter from what is selected in the combobox on my WinForm, to generate the report

Such as the part of my query " WHERE number LIKE 'WinForm Combobox Text' "

Is there a certain syntax to write in the query statement to get the parameter from the combo box

I tried this, but does not work: WHERE number LIKE {me.cboNumber.text}

I have searched the net to try and find an example of how to do it and could not find anything. Any help would be appreciated.
