made a boo boo with prices

I seem to have made a screw up somewhere.
When I make a new product. I set the price to say £20. Then when I save it - the price on the insert screen says it is 0 - even though the detail still says it is £20.
The products are not set to free products, so I'm not sure what I've done.

See
http://oldersoftware.co.uk/index.php?main_page=product_info&products_id=1
for example.

Sorry about this. Feeling v.stupid and I really don't want to reinstall everything.

Thanks

A bit more info

When I go to Price Manager the price - (even though in the record it is set to £18) says 0

I'm going nuts. When I go to the category and then select the product and edit - there is a price in there of £20, but when I save it shows the product details but the price is set to 0.

Sorted it.

I had amended the US currency to GBP and it had all spacked up.

Thanks

Phil

Thanks for sharing the resolution Phil. Many people get stumped on the same issue.
