Change ammo widget based on data asset

Hi,

I have a weapon wheel with a widget that displays the ammo for each gun which I store in an inventory component. I’m trying to now make it so that the ammo for the currently hovered weapon shows in the middle of the wheel.
Setting my data asset here works fine but I want to dynamically change this based on the selection

For some reason changing this here has no effect. I know a lot of it isn’t plugged in there but I was trying to manually check with the pistol ammo first

Any ideas?
