How to link votemanager to the gamemode?

[Wisam]

Hey..

So i have a server with Bomb Da Base gamemode(based on assault) and EVRYTHING is working perfectly 99.9%, expect one thing its the votemanager.. im sure you know the assault gammode every map has 2 rounds, but the problem is that i have to keep changing the map manually all the time, there isn't a votemap or a next random map i tryed to fix it but failed..

Myabe i just have to link the votemanager or the mapcycle to the gammode? if you know anything please help me
