I copied the score muliplier code as follows:

//Score multiplier:
//The “numround” variable defines when the multiplier will start being applied to the score.
//The “mult” variable defines the value that the score will be multiplied by.
if (numRound ==7){
mult_txt.text = “Double”;
mult = 2;
} else if (numRound>7){
mult_txt.text = “Double”;
mult = 7;
}
if (numRound ==13){
mult_txt.text = “Triple”;
mult = 3;
} else if (numRound>13){
mult_txt.text = “Triple”;
mult = 13;
}
//end score multiplier code

As I said above, I needed the Double round to start at Question 7 and the Triple rounds to start at Question 13.

Hope this helps!
