Hi i make a function to claculate the mean of a random 6-item array, the random array copied to a div in table , i make a function to get a random array
now i want to read this saved array and call the function calcMean ()
and take the mean value and the min also the max of the array

    <div >
    <form  action="" method="post" name="meanForm"  onsubmit='return false'         id="formmine">

      <table width="100%" border="0" >
    <tr>
  <td colspan="3" style="background-color:#06F ;color:#FFF">Answer this   problem</td>
    </tr>
 <tr>
 <td style="color:green; font-size:20px">What is the mean of these numbers </td>
    <td colspan="2"><div  id="numbers"></div>
      </td>
       </tr>
    <tr>
     <td colspan="3"> </td>
    </tr>
  <tr id="answerANDpic">
    <td height="62" colspan="3"  align="center" > <input name="" type="text"      size="15" maxlength="100" height="50" style=" border: solid #0C0 ; border-width:thin"  id="answer"   onkeydown="searchm(this)"/> </td>
      </tr>
   <tr>
     <td colspan="3"  ><div id ="explain" ></div></td>
  </tr>
 <tr>
    <td> </td>
    <td><input name="" type="button" id="newEx" style="background-color:green ; color:white"  align ="left" value="New Problem" class="send_feed"  onclick="randomArray(6,0,99)" /></td>
     <td><input name="" type="button"  id="solution" style="background-color:#606 ; color:#FFF  " align="left" class="send_feed" value="Solution"  onclick="solution()"/></td>
    </tr>
</table>



</form>
</div>

in JS

var myNumArray = randomArray(6,0,99);

function random_number(min,max) {
    return (Math.round((max-min) * Math.random() + min));
}

function randomArray(num_elements,min,max) {
   var nums = new Array;

   for (var element=0; element<num_elements; element++) {
       nums[element] = random_number(min,max);
    }

    document.getElementById("numbers").innerHTML=nums;
   
}




function calcMean(nums) {
    var num=0;
    for (var i=0;i<nums.length;i++) {
        num += parseFloat( nums[i], 6 );
    }
    var divide=num/nums.length;
    var mean=(parseInt(divide,10));
    var maxi = Math.max.apply(Math,nums);
    var mini = Math.min.apply(Math,nums);

    return [mean,maxi,mini];
}

function searchm(ele) {
    if(event.keyCode == 13) {
        // alert(ele.value); // i get the value and put it on alert        

        var inans= ele.value;
        return inans;
    }
}



function solution (){

//read the array which saved in div id="numbers"
//call calcMean();
//get the mean ??
//get the min and max ??
}
