You can start by replacing

eval('document.frm.'+pos+'.value')

with

document.getElementById(pos).value

Now i have changed it to dom Object Model
The code is as follows:

Code:

function validateAllFields(objForm)
	{		
		      var count=document.frm.hdnCount.value;   
        	  var data="";
			  var checkStatus;
			   for(var i=1; i<=count; i++)     
    				{
					checkStatus=false;
					var pos1='txtAnswer_'+i;
					debugger;
					var strAns=document.getElementById(pos1);
					
					var pos='hdnQuestionID_'+i;
					var strQuest=document.getElementById(pos);
					
					if(strAns.Value!="")
						{
						data=data+"~"+strQuest.value+" $"+strAns.value;
						checkStatus=true;
						}
					
						if(!checkStatus)
						{
						alert("Please choose anyone from this question");
						document.getElementById(pos1).focus();
						return false;
                        }
					}
					alert(data);
					if(data!="")
					{
					data=data.substr(1);
					}			
		 document.frm.hdnQuestionAnswerData.value=data;      
         document.frm.mode.value='WARMUP';     
           return true;
		
		}
