Hi I’ve made a code that rolls dice untill it gets doubles, I’m trying to make a Counter for it so that it counts how many times it rolls untill it gets doubles. Can someone help me get the counter to work?

function RollUntilDoubles()
// Assumes: document.DiceForm.Output is available for output
// Results: rolls and displays dice until doubles are obtained
{
var roll1, roll2, repCount;
repCount = 0;
while (repCount > 0) {
roll1 = RandomInt(1, 6); // roll and display dice
roll2 = RandomInt(1, 6);
document.DiceForm.Output.value =
“You rolled: ” + roll1 + ” ” + roll2 + “n”;
while (roll1 != roll2) { // while not doubles,
roll1 = RandomInt(1, 6); // roll again and display
roll2 = RandomInt(1, 6);
document.DiceForm.Output.value =
document.DiceForm.Output.value +
“You rolled: ” + roll1 + ” ” + roll2 + “n”;
}
document.DiceForm.Output.value =
document.DiceForm.Output.value + “DOUBLES!”;
document.DiceForm.count.value =
document.DiceForm.count.value + repCount;
}
