What am I doing wrong?

[linnet27]

Hi

I am trying to set up an offer of £1 off specific items. I have put them in a group, ticked "enabled", based on value, trigger 1p, Reward Type £ off, Reward Amount £1, ticked "only one reward per order".

I've published to web but the item is showing as 1p discount, not £1.

Help please!!
