Can I send a Transform as parameter with BroadcastMessage()?

I have encountered an error (which is stumping me) while trying to use BroadcastMessage() which states:

Failed to call function GotAHit of class CountInAreaMission Calling function GotAHit with no parameters but the function requires 1.

This seems weird as my BroadcastMessage call looks like this:

function SomethingImportantHappened( pos : Transform)
{
    BroadcastMessage( "GotAHit", pos , SendMessageOptions.DontRequireReceiver );
}

The called function looks like this:

function GotAHit( ove : Transform )
{
     //do super secret stuff w the transform
}

I have successfully sent an int through the same functions without any trouble. So the question is: Can I send a Transform as parameter with BroadcastMessage()? or is BroadcastMessage() only for primitive variables? or am I at fault?

Thanks for any and all replies!
