    var nam = document.myForm.name[x].value;  <<< error?
    if(nam>1000){
        document.myForm.name[x].focus;   <<< error?

Answer 1

document.myForm.name['name'+x].value; and document.myForm.name['name'+x].focus()

Answer 2

Working Example

function getValue(nameValue){
    var element = document.getElementsByName('name' + nameValue)[0];
    if(element){
       if(parseInt(element.value, 10) > 1000){
           setTimeout(function(){
              element.focus();
           },0);  
           alert ("input > 1000");
       }
    }
}

Usage:

getValue(1);
