$dummy - A dummy variable, it is only needed for the function to work, it is not used.
n - A seed value that you can use to make the random number generator return the same value each time. This value is not required, in general, it should be omitted.

Use this function before using the rand function for the first time in your Form Processor configuration file.

#Randomize and generate some dice rolls

$Dummy_Value=srand();
$DiceRoll1=int(rand(6))+1;
$DiceRoll2=int(rand(6))+1;
