You'll have to end the switch statement before setting return 1, like this

Code:

case 29: // ARMY Armory
		{
		    ShowPlayerDialog(playerid, 29, DIALOG_STYLE_LIST, "Army Lockers", "Nightstick ($50)\nMace ($100)\nDesert Eagle ($200)\nShotgun ($100)\nMP5 ($600)\nM4 ($1000)\nCombat Shotgun ($1500)\nSniper Rifle ($2500)\nPainkiller ($100)\nVest ($200)", "Choose", "Cancel");
               }
       }
	return 1;
}

Hope it helped
