Hi Andrea,
I would love to be able to help you... I'm not the best on technical matters... but what I do, is go via my ticker... if you click on my ticker the link should come up for you.
When I put in my weight and height it worked out the statistics on the ticker and then I inputted the figures manually on my profile on the cp.
I am not sure if this is any help, sorry I can't be of much use, but someone will know the exact way for sure....
Always here if I can help...
Sending a loving hug as always Sugga xxx
