This is crazy Stu, the page is not the same. There are several differences
including the absence of the dropdown in question. I wonder if something
I have entered/changed/not entered earlier in the process has caused that dropdown to be not offered. Actually I think that is irrelevant as too many other things are different.
I only just noticed that you said your screenshot is .com, so I'm presuming that they must be different. Perhaps you can
try .com.uk at your leisure, and let me know what you find.
thanks raymo
