What am I doing wrong with Google Product Categories

[Bedspring]

Hi,
I have done as it says here http://community.actinic.com/showthread.php?t=51292

in variables>product>category> initial value I have used "http://community.actinic.com/showthread.php?t=51292 "
but when I go to Product>properties all I see in the Product category box is Use Parent(mattreses) however even when I have gone through several products and pasted in " http://community.actinic.com/showthread.php?t=51292"
mashed and uploaded it still shows an error
I have used the correct Google taxonomy
Regards Steve
