non-unique array generation and element count

I am currently building a tool for a friend that runs a live action rpg that has a downtime system between games.

Basically the intended result is for her to be able to enter numbers into some form fields to get a total number of dice to be rolled.

this field would then dictate the size of the random non-unique array with numbers between 1 and 10, to be generated.

we also have a difficulty threshold in the form.

I need to not only be able to generate the array, but get a total count of all elements with a value greater than difficulty form id.

for example: total dice used: 230 , difficulty: 4, output x where x= total number of elements greater than 4.

keep in mind that tdu and dif will be changing every time.

I currently have a form field that displays total dice used (var totalDice = document.genera tor.txtTotalDic e;) and difficulty (var totalDif = document.genera tor.txtTotalDif ficulty;)

need the final output to go to a form field -- Total Successes (var totalSuccess = document.genera tor.txtTotalSuc cess;)

any help would be appreciated...
