Perl keeps telling me "Use of uninitialized value in modulus (%)" in this line where I have an if statement (and no modulus). If I change that line to remove the part after the &, it works fine... both of the variables are defined if I try to print them somewhere near there. 
for($x = $prevmax;$x<=$max;$x++)
   {
   
      $n = sqrt($x);
      $i = 0;
      while ($x%$p[$i] !=0)
      {
         $i++;
         
         if (($n < $p[$i]) & ($x > $p[-1])) # error here
         {
            print (1 & ($x > $p[-1]));
            push(@p,$x."\n");
            last;
         }
      }
   }

Could anyone help me? Thanks

Considered by xdg: "retitle 'uninitialized value in modulus'"
Unconsidered by davido: Final vote of 11/26/0 indicated significant opposition to retitling.
