Help can't add postage fee to a sale in 'send invoice'- the sum I type in disappears when I preview!

[gaussgirl]

Help! The original item was offered as pick up only but someone offered to pay postage which I calculated and offered. Now he's won and wants to pay but none of the 3 options in the drop down boxes beneath the subtotal (ie the auction's end price) will allow me to fill in 9.30!). I type it in, and it disappears. If I 'review invoice before sending' it's not there, just the end price.

What am I doing wrong?

I tried to put it in 'add dicounts (-) or charges(+) so I put +9.30, and it again wipes it out saying 'please enter a valid amount for discounts or charges'

wtf is INvalid about +9.30? The pound sign is already there

are you recalculating after you have entered the amount? if you are - that's why it disappears

You are indeed a genius.

You'd kind of think 'recalculate' MIGHT mean 'do the sum again now that I've added postage to it' wouldn't you?
Bloody ebay! I now remember why I use it so rarely!!

Many thanks, six. I'll help you find your monkeys.
