Can't assign value to symbols

Hello,

Situation:  I have a table that contains parameters and sets of values 
that I want to assign to the parameters for the purposes of running a 
simulation.
- parameters = {{a,b,c},{1,2,3},{4,5,6},{7,8,9}}
- want to assign values in a given row to the symbols listed in the 
first row.
- tried using:  MapThread[  #1 = #2 &, {parameters[[1]], parameters[[3]]} ]
- fails with error  "Tag Slot in #1 is Protected"
- tried adding Unprotect[#1] and a variety of other attemps, but can't 
get it to work.

Anyone know how might accomplish this?

Thanks,
Lee
