问题
I am trying to get a value fro query string and assign that value into a textbox. I am able to get the value from query string but unable to assign it to textbox.
document.getElementByName('Contact0Email').Value = email;
Tried the above code but doesn't seem to be working. Though the alert of email gives the right value.

You need a lower-case value and a plural Elements:
document.getElementsByName('Contact0Email')[0].value = email;
You need the [0] to get the first element in the list. Names don't have to be unique like ids.
