Can LCD shield & an SD shield use the smae PINS (11,13)

I connected an SD shield to a Lilipad, but now I want to add an LCD shield as well. But these use the same pins. What to do now?

Both a unique Slave Select connection. Typically this is pin 10. But can be any you define.
You then control each one by taking its SS pin low, doing your writes, and taking SS high when done.

What LCD shield and SD shield? Will need links to them to decide. If they are both SPI slaves and share same SS like CrossRoads guessed, you will have some snipping to do with a wire cutter. Can be done.
