Making a tool place on click?

Hello! Thanks for clicking on this question. I'm trying to make a ladder placement tool. When the player equips the tool and clicks somewhere on the ground, the ladder is supposed to appear on the ground, and it's supposed to become visible and anchored. The problem is, it won't place the ladder... it just places a block. I've provided the scripts, the children of the tool, and the link to the tool. Thanks!
