Sorted this one out.

In the Shipping Charges we had the weight range as 0.0 - 0.00 because we don't use weight for delivery charges. The product the customer was ordering had the weight field entered and this was casuing the problem.

Two options:-

set the product weight to 0
or
set the weight range in the shipping charges section,e .g 0.0 - 1000.0

The only reason we sorted it quickly was the customer was ordering one product and it was a fairly new entry - someone liked us today !
