I am making a batch game or .bat

I've never used batch before. just javascript. I just wanted 2 try something a little different.

I found this how to on youtube on batch rpg games video on youtube but i haven't heard any thing back from the person that created it.

Everything is working fine so far but i have ran into a big problem. When ever i buy something from my shop it won't equip me with it. It takes my money but it don't do anything else. Here is the program code. If anybody knows what i have done wrong will you please tell me.
I also haven't started on the battle system yet. This is what i have so far. The saving and loading work fine, it is just the shop that i am having problems with. If you want 2 see what i mean for yourself then just copy and paste it into notepad and save it as what name you want .bat and make sure 2 save it under all files.
