Please provide more details about your problem...
You might want to use the following cvars and cmds:
Code:
// Veto stuff
wm_pugsetup_maplist_file "configs/maps.txt", "Maplist to read from. The file path is relative to the sourcemod directory."
wm_pugsetup_randomize_maps "1", "When maps are shown in the map vote/veto, should their order be randomized?"
wm_veto "1", "Veto Style: 0 = off, 1 = Bo1, 2 = Bo2, 3 = Bo3"
wm_veto_bo3 "0", "Veto Style: 0 = Normal, 1 = New"
wm_veto_random "0", "After the vetoing is done, will a map be picked at random?"
// Veto cmds (use via console or replace sm_ with ! or / for chat)
sm_vetobo1 - Veto_Bo1, "Ask for a Bo1 Veto"
sm_vetobo2 - Veto_Bo2, "Ask for a Bo2 Veto"
sm_vetoBo3 - Veto_Bo3, "Ask for a Bo3 Veto"
sm_veto - Veto_Setup, "Ask for Veto"
sm_vetomaps - Veto_Bo3_Maps, "Veto Bo3 Maps"
