Creating a VI to use in another VI which can take input help

[MrSafe]

First off my title is horrible but I could not do better.

Problem:

I have a VI which is attached I would like to create inputs for Start Frequency and Stop Frequency. Basically this VI ( which I will call File A) will be used inside another VI (File B) where File B will apply the inputs needed for File A. However my problem is when I insert File A into File B's block diagram I do not see any inputs.

hmmm..the discription is very vague I have managed to find the connector pane but it doesn't explain how to create a subvi.

Every VI is essentially a sub-vi. By connecting controls and indicator to the connector pane you declare the routine call. If you use autowiring, clicking inside the connector pane and sequentially the controls you want to export you will get what you want.
