I get

(149) : error 008: must be a constant expression; assumed zero
(166) : error 008: must be a constant expression; assumed zero

arrays and variables

int g_weaponLevel[MAXPLAYERS + 1]; 
int maxWLevel = 20;
int wLevelPrice[21] = { 6, 10, 14, 18, 22, 26, 30, 36, 42, 48, 54, 60, 68, 76, 84, 92, 100, 110, 120, 130};

Line 149 and 150

char weapon[128] = wLevelWeapon[g_weaponLevel[client]];
	GivePlayerItem(client, weapon);

line 165,166,167

	int price = wLevelPrice[g_weaponLevel[client]];
	char wName[128] = wLevelWeaponName[g_weaponLevel[client]];
	char pstr[64];

I'm trying to do like a level based weapon system

Strings are not pointers in Sourcemod. You will have to use strcopy.

Thanks for your help ^^ <3

You don't have to use strcopy. However, initialization (char s[128] = other) and assignment (char s[128]; s = other) are different. Initializations have to involve constant expressions, as the error says, so you can only do the latter.
