Selectable Menu

I make a 2D game and I want to make a selectable menu ( every time I touch a button my game start , not letting me to choose another thing in the menu). For example I have MAPS and Characters option in menu . The player choose what character and map wants , but every time he just touch one map the game starts not allowing to chose the character . How can I make the menu selectable and at the end the player just press the button START and all his option to be save

maps should all be part of a toggle group and the characters should be another toggle group

use this tutorial for toggle groups

then A DIFFERENT BUTTON THAN ANY OF THOSE, uni010 was pointing this out, should be what loads your scene.
