As the plural in getElementsByName   implies  does it always return list of elements that have this name  So when you have an input element with that name    lt input type  text  name  Tue  gt    And it is the first one with that name  you have to use document getElementsByName  Tue   0  to get the first element of the list of elements with this name   Beside that are properties case sensitive and the correct spelling of the value property is  value

How to address your textbox depends on the HTML-code    lt  -- 1 -- gt  lt input type  textbox  id  Tue    gt   lt  -- 2 -- gt  lt input type  textbox  name  Tue    gt    If you use the  id  attribute   var textbox   document getElementById  Tue      for  name    var textbox   document getElementsByName  Tue   0     Note that getElementsByName   returns all elements with the name as array  therefore we use  0  to access the first one   Then  use the  value  attribute   textbox value    Foobar

Sounds like we need to assume that your textbox name and ID are both set to  Tue    If that s the case  try using a lower-case V on  value

There are two issues in your code    Use getElementByName instead of getElement  s  ByName use the value in lowercase instead of Value
