Hi all,
I'm trying to get into the SX again after a short time away.  I haven't used the subroutine function and was trying to use it.  Could someone tell me what I'm missing.. I'm sure it's a simple..

 

It's giving me an invalid parameter on the subroutine CLICKS, on line High LED4.  Is this because I should be passing a paramenter there?  I don't get it.

 

Thanks,

Russ
