Nested Select Statement in Access 2010

I need help with creating a nested select statement.  I have 2 tables shown below (they contain more fields, but am only listing what is applicable:

Requirements Table
U_RQ_ID
U_RQ_Description


U_Applicable Configurations Table
U_RQ_ID
U_Vehicle_Config_ID

I have a list box that the user will select a vehicle configuration ID and want to be able to pull up all the requirements for that vehicle configuration ID.  A requirement can be applicable to several vehicle configurations.

Here is the select statement I am having trouble with.  The error I am receiving is:  Too few parameters:  Expected 2.

Set rst = db.OpenRecordset("Select * from U_requirements where U_requirements.[U_RQ_ID] IN (Select U_Applicable_Configs.[U_RQ_ID] from U_Applicable_Configs where U_Applicable_Configs.[U_Vehicle_Config_ID]= Me![U_Vehicle_Config_ID])")

Thank you!
