CT600 (Short) Trading Loss?

[zarjaz]

I have a very (very!) small company.
I am preparing CT600 for end of month - I find the new online HMRC version confusing.

My total turnover for 08/09 was just £2520, with bank interest of £1. My costs for that year were £3818. So, I have a trading loss of £1397.

I have 4 straightforward questions:
1. I put £2520 in box 1 of CT600, but as I have no actual profit, do I leave box 3 blank?
2. I put my £1 interest (!) in box 6?
3. What goes into box 21? Is it £1 (sum of 5, 6, 11, 14, 18)
4. Do I put my trading loss of £1397 in boxes 30, and 122?

And that seems to be it?

Any advice is very much appreciated.
