Textarea validation

hi...i can't seem to validate textarea..

function TextAreaRequired(Form, Field)
{
  var length = eval("document." + Form + "." + Field    + ".value.length");
if (length == 0)
      {return false;}
      else
      {return true;}
}
if (!TextAreaRequired(FormName, 'Work_Scope'))
{
alert("You must enter your job scope");
return false;
}
</script>


<textarea name="Work_Scope" rows="5" cols="44" wrap="virtual">[Enter your job title, scope etc. Max. 255 characters]</textarea></td>

What is wrong with this? Thanks!

first of all FormName is not a variable.......
and then you are using the formname variable before the form is created...
