Because they had taken it off as it was the 04 application form not the 05 application form.
They hadn't finished the 05 form so I rang them and they said they would send me one as soon as it was available, so I haven't gone back on to see if they've put it back on.
Kind of moot really as DP don't have their 05 application forms out yet either .... going round in circles a bit here ...
