Object referance is not compatible with object referance

Hello,

I’m following Slot Based Inventory tutorial to create inventory system.

At 25:00 in the video ForEachLoop and UpdatePrice “*array element” *and "target" link connected with no problem.
But when I try to connect those I’m getting error “Object referance is not compatible with object referance”

this experienced the rare forum glitch where new posts get added to the very end of the forum section. Giving it a ‘bump’ to help surface it
