I'm making a stupid-hard map where the mystery box is 10,000 and the only wall weapon is the kar98 

Is there a way to change the price? Thank you!!!

Go to raw/maps and copy _zombiemode_weapons.gsc to you mods/YourModName/maps

Open it with text editor and find this:

treasure_chest_think()
{	
	cost = 950;

Change the cost to whatever you want, then find this:

player maps\_zombiemode_score::add_to_player_score( 950 );

And change "950" to whatever you want

That should work, sorry for any english error 

EDIT: Don't forget to mark "_zombiemode_weapons.gsc" in your Launcher when you compile your mod.

So i did this, but the box still costs 950... i set it to 10000.. do i need commas?

You need to change the "zombie_cost" KVP in Radaint for all the boxes' trigger you have to 10000.

You don't need to edit this actually:

treasure_chest_think()
{	
	cost = 950;

And you also have to edit this line:

self set_hint_string( self, "default_treasure_chest_" + cost );

With:

self setHintString( "Press & hold &&1 to use box [Cost: " + cost + "]" );

Probably you'll need to change the text for the hint string, because I can't remember now what it says originally.

So I change the trigger on the mystery box? It's a prefab.. Should I just click it and press n? Sorry I'm new at this

To explain this a bit more in-depth, a prefab is essentially a combination of several parts. This can be models, triggers, brushes, etc. They're "stamped" together, so you can move the prefab around, but not each part of it separately. To do this, you need to Un-stamp it, which splits the frefab up. The parts will stay in position, but will now allow you to move and edit each part of it separately.
