Some of the things that I have had to tweak were because of slight changes between 11 and 12 calendar is there any documentation specifically for 12 as I am being directed to 11 each time
thanks

Documentation for the free calendar in 12 is here: http://www.seedcode.com/pmwiki/pmwiki.p ... ndarFree12

The links inside the free calendar should all be pointing you there: are you getting referred to the 11 docs from somewhere else?
