random key

function randomgen(upper,lower){var ran=Math.floor(Math.random(lower) * (upper - 1 + 1)) + 1; return ran}

alert(randomgen(15,5))

this is the code but it generates randoms not as intended ( I would like to make figures between 5 and 15.

Actually you need the following to include the numbers in your range:

function randomgen(upper,lower){
  return Math.floor(Math.random() * (upper - lower + 1)) + lower;
}

Hi Fuad,

try:

function randomgen(upper,lower){

return Math.random() * (upper - min) + min;

}
