Problem: I am getting use unitialized all over the place in this snippet even though I'm testing if the variable exists before I use it.

Background: If $foo{$bar} exists I want to take the value into a variable, increment the number then reassign it to the database. If $foo{$bar} doesn't exist I assign a value of 0 then increment the same way.

One last question, I was told I had to nest my statements if I wanted to do use an If inside of another If statement an so forth. Problem was I searched the site and the web for what 'nests' are and didn't find anything. Do they mean empty blocks like I'm using?

Thanks so much for your help! 

       { 
          if (exists $dbm{$lost}) {
        $youlose = $dbm{$lost};
        $youlose++;
        $dbm{$lost} = $youlose;    
                                 }
          else {
        $dbm{$lost} = 0;
          
        $youlose = $dbm{$lost};
        $youlose++;
        $dbm{$lost} = $youlose;
               }
       }  
      }
