Cant seem to call structures in blueprint in 4.6 preview?

just as it says i created a structure added 2 variables and cant seem to call them at all from another blueprint. from what i under stand is now in order for inventory’s to work correctly they have to run through a structure or you lose your data every 60 seconds. so im trying to replace my original arrays with ones set up in a structure but i cant seem to call the structure.

still looking for help on this if anyone knows how to fix this
