Hi Rod,

Thanks for your help.
I have actually discovered that the items are not going over the 20kg weight. They are less than 20kg.
It seems to be the dimesions that are causing the error.The maximum girth I believe is 140cm... width + height not to exceed 140cm.My packages are bulky and are fine if done individually(less than 140cm). However if I select 2 packages then they exceed the 140cm MAX even though they are 2 seperate articles it calls up the Error.
Seems it is not able to differentiate between multiple packages ?

Cheers
Matt
