Clicking won't throw object

So when i am ingame, i can't get this object to be thrown, it just tells me that there is no input set up for it. I can pick it up because i added an input for that, but i don't understand how to edit the other button inputs to get them to work.

how do i get them to work properly?

Any thoughts will help! thanks!!
