Access forms-2007

Hello everybody,

I am using Access 2007 version and in my form I am using a label box with underlined option and click event and if I enter a single policy number(which I enter using the first form)and click the policy num it navigates to the third form and if I click one number from a list of policy numbers it goes to the third form but it does not display any records. Why? Any help in this will be much appreciable.
Thanking u.
