Thanks for the tip on the randomize code. Though how do i store the amount of rolls as a public variable?

I have to do a project where there are 5 die, and each player gets 3 rolls per turn. The player then hits cmdPlayer1Roll, which randomizes the die 1-5. The player can randomize the die 3 time but at the end of the 3 rolls they need to have selected 3 numbers from the die. The first player to 1000 wins. I have to what i believe, successfully coded the randomize on the click of cmdPlayer1roll.
Here is a very fast gyazo gif of what i have coded...
