Problem with Key Mapping on Blackboard

So I’m getting into AI and I came up to an early issue. I created a new Object Key and despite that, it refuses to appear within my list of Blackboard keys so that I can assign functions to it.

You can see there in the bottom corner that “GuardTarget” exists, but it does not appear under my list of Blackboard Keys for the drop down menu so I cannot attach it to my Move To.

Hi dude, have you set to “GuardTarget” blackboard key as an actor? Goto the blackboard and expand GuartTarget object, click the drop down that appears and type actor select it and boom, should work!

In fact, I did not. You fixed my problem perfectly.
