Stuck on some code....

Currently Cell Z2="Line1".

I would like to write a macro that says essentially if Z2="Line1" copy cells Z1000:Z1200 and paste into Cell A1 on Sheet titled "Sheet1".

If Z2="Line2", copy cells Z1000:Z1200 and past into Cell B1 on Sheet titled "Sheet1"
If Z2="Line3", copy cells Z1000:Z1200 and past into Cell C1 on Sheet titled "Sheet1"
On through "Line100"

Any suggestions? Thank you!!
