Wire class conflict

[wannabecontroller]

Having an issue trying to connect a reference to a sub VI.

 

I have creaed a control refnum on the front panel of the sub VI and changed its properties to type bool 

Then connected the control ref to a front panel terminal. 

When i try and connect the reference from the main to the sub vi i am getting an error that says wire conflict class.

Can you show us what the control on the sub VI is please. Also the Context Help window might provide some insight into why this wire is broken.
