I am having problems in issuing an invoice as the system will not allow me to add the Postage and Handling charge.

[christhegreenie]

I have recently sold an item.

I selected the "Ask the Seller for a postage/freight charge" option as the item is quite large. I figured that the postage or freight would vary considerably with distance and I was unsure as to whether the buyer would be wanting tracking or insurance etc.

The buyer has requested an invoice including Postage and handling so that they can pay.

I can add the P & H (freight) handling charge but the system reverts to a blank field when I select "recalculate".

I have tried logging off and on again to "clear" the system but to no avail.

Am, going around in circles!

Has anyone got a solution to this annoying problem?
