Why does my touching script not work?

  1. What do you want to achieve? Keep it simple and clear!
    I want to make it so that if a part is inside of my viewmodel part for my placement system then it will go red. My script used to work perfectly and now it just stopped working for some reason. Here’s my code :

Disabled BuildingHandler - Roblox Studio 2023_09_21 20_12_55

  1. What is the issue? Include screenshots / videos if possible!
    The script just stopped working. Here’s a picture of it not working :

The part is just touching the other part and it goes red, the script checks to see if a part is inside of the part, not touching it.
