Thanks for the response! I was looking into how %seen works and realized where my code was wrong

I added a line above the loop: my %table2a = keys %table2 and then changed my if statement: if (exists ($table2a {$x}))

Now it's working just as expected. You'll also notice that the parentheses in the if statement changed as well.
