Combining drills?

[Your Computer]

It just tells me 'combination does not work' when I try to combine them. It seems as if it isn't running any of the scripts in inventory.hps for some reason.

Where did you put your inventory.hps file at?

I... wow. I put it in the maps folder, and it works now. I facepalmed vigorously. Thank you so much for being so helpful. I hope this thread is useful for anyone else hoping to combine inventory items!
