You don't have any elements with the name you're using ? – adeneo
what is your html code? – kp singh
i am getting value from this syntax as well as error. :(. my HTML code is, <input id="xScoNum-5534" type="text" name="xScoNum" size="30" maxlength="30" value="44528-3" style="width: 0px; visibility: hidden;"> – Deepak Parmar
as per your comment thats not the proper usage of getElementsByTagName, see here:: developer.mozilla.org/en-US/docs/Web/API/… – Sudhir Bastakoti

document.getElementsByName(...).0.value' is null or not an object usually occurs when you're trying to access an element that does not yet exist. The problem appears to be as JavaScript runs before the element is added. The element must be added to the DOM first, then you can access it.
