I need a spreedsheet to help keep weight loss and percentage weight loss for up to 6 people
I would like it to look like this

Date all the way across by week from 1/31/13 to 11/28/13 I know how to do the date formula to make it put the date for next week across kinda like this =b1+7

then I would like to go like this

the numbers and names will just be example

Jane starting weight current weight current weight current weight ect all the way across
200 195 190 185 ect all the way across
this block would be percentage lost calculated as each current weight is put in
this block would be the actual lbs lost all the way across

Next person with the same above calculations

next person with the same above calculations and so on

if anyone can help me with this i would so much greatly appreciate it..

thanks
