how to add a parameter to a Sequence Call

OK, I am a newbie at this TestStand thing, but I know I have done this before and just can't figure it out today.

In the Main Sequence I have a Sequence Call to Setup Testhead.  I am passing 9 parameters to that subsequence.  I want to add another parameter (to be used to conditionally bypass part of the subsequence).

So, I went to the Setup Testhead subsequence and added a new boolean to the parameters (Do_PLD_Prog).  See attachment named Subsequence View.jpg.

Why does this new Parameter not show up under the list of Parameter Names for the Setup Testhead Sequence Call?  See attachment named Main Sequence View.jpg.

Thanks,

Steve
