One issue is with the testing of the numbers as if they were Boolean (if (wholeNumber && wholeNumber2)). If either number input is 0, this will be interpreted as false just as a NaN would be. To avoid this, you can check the numbers using isNaN: if (!isNaN(wholeNumber) && !isNaN(wholeNumber2)).

Also Math.random does not take an argument, and the formula used is not correct for selecting a number inclusively between two limits. The correct formula would be: Math.floor(Math.random() * (wholeNumber - wholeNumber2 + 1) + wholeNumber2).
