Extra Tokens at end of expression

Getting this error when attempting to make a more complex if statement.

‘syntax error in expression “[cequal $pv1_31_1 $emr] $$ [cequal $pv1_3ed $ed]”: extra tokens at end of expression’

Here is my if statement.

      if {[cequal $pv1_31_1 $emr] $$ [cequal $pv1_3ed $ed]} {  

           return “{CONTINUE $mh}”

         } else {

         return “{KILL $mh}”

        }  

     }
