in reply to sorting an array from two sources

We're going to need more information. What are you doing with $sortfield. All the code does is keep changing it based on the existance of $IDNumber in %sort_file. Did you snip too much out of your loop? Did you mean to make $sortfield a hash or array of some sort. Your logic is sound up until that last if statement which just keeps changing the value of $sortfield over and over.

Later

P.S. Even if you are missing too much out of your loop, I think I spotted the logic error in your if statement. You assign $total_points when what you really want to assign is $sort_file{$IDNumber} since it is storing the value of $total_points for that hash key. Change it to: 

if (exists ($sort_file{$IDNumber} )) {
       $sortfield = $sort_file{$IDNumber};
   }     else {
       $sortfield = "";
   }

    Thanks very much for your input, pzbagel.

    I'm afraid I was careless in putting together my sample code. $sortfield is the first field of the db as follows: 

    ($sortfield,$undef,$IDNumber,$Email_address,$Page_Name)=split (/\t/,$l
+ine);

    What I want to achieve is each time the main db is iterated, the second db is serched for the IDNumber. If it exists the $total_points will be stored in the $sortfield for that line, otherwise it is undefined. I can then sort the main db according to the values of $sortfield.

    I tried your update above, and thought it made sense. However it didn't work so I think my logic must be awry somewhere along the line.

    Thanks once again
