Input Disabled

Hi Folks,

I'm having with an input field on my form. I'm getting the user to use a JS date picker to populate a date field. To stop users entering the date manually, I've added the disabled attributre so it is greyed out.

Here is the code for my form:

<input type="Text" id="date1" name="date1" value="" maxlength="15" size="15" disabled="disabled" >

However, when I add the disabled attribute, I always seem to get the error below on my action page

Can anyone help?
