Back with new Problem

I have Created a New Project and Made Different TC's in the Suite.
Now I am having Problem: I have a Function named Screen Validation
I wrote it in Code Module and Was using it by Drag and Drop.
Now the Problem is I want to get a value from this Module(Screen Validation) to the Main Test Case but I think that is Not Possible. Or is it?

Is there a way we can use this in any Function Library and call the function any number of times we want from a Code Module?
If Yes then How?

Because I have seen the Posts of Creating Function Library and were not of any Help.
Please Help on this ASAP.
Support team any comments?
Regards,
Deepak
