[Duelpro]

I made an event where the player has to press 4 diffrent switches
in the right order.
How can i do this?

Well, first switch make it add 1 to variable.

For the second switch, make a new page which requires that variable to be 1 or more. Make it also add 1 to that variable.

For the third switch, make a new page which requires that variable to be 2 or more. Make it also add 1 to that variable.
 
For the fourht switch, make a new page which requires that variable to be 3 or more.
