variable not found with loop?

Shell Programming and Scripting

I cannot seem to pass the value of the variable assigned in the "else" statment below to an "if" statement outside of the loop. When I debug using "set -x", I find that the value of "$A" is empty. Is there something I'm missing here? Code is below:

do
   if [[ "$var1" = "L" && "$var2" = "e" ]] then
      echo "Good Match" $var1
   elif [[ "$var1" = "T" && "$var2" = "t" ]] then   
      echo "Good Match" $var1
   elif [[ "$var1" = "P" && "$var2" = "c" ]] then
      echo "Good Match" $var1 
   else 
      echo "No Match" 
      A = "N"
   fi
done

if [[ $A = "N" ]] then
      exit

TIA.

No spaces. It's
A="N"
