Problem with collect

  • To: mathgroup at smc.vnet.net
  • Subject: [mg6425] Problem with collect

There is a larger expression

ss^2 (bla+bla+bla ...) + vv^2 (bla+bla+bla...) + ss(bla+bla+bla...)vv  

which is Expanded[]

I want it in the way mentioned above. Therefore I tried

Collect[expr, {ss^2, vv^2, ss vv}]

which did not work.

What is wrong??
