When running your code, I get the following error messages:

Missing right curly or square bracket at tmp.pl line 14, at end of lin
+e
syntax error at tmp.pl line 14, at EOF
Execution of tmp.pl aborted due to compilation errors (#1)
    (F) The lexer counted more opening curly or square brackets than c
+losing
    ones.  As a general rule, you'll find it's missing near the place 
+you
    were last editing.

Uncaught exception from user code:
        Missing right curly or square bracket at tmp.pl line 14, at en
+d of line
syntax error at tmp.pl line 14, at EOF
Execution of tmp.pl aborted due to compilation errors.
 at tmp.pl line 14

Maybe you want to read the error messages and correct the issues raised by them.
