And is $ref a typo or your actual code?
Try gnorks advice, and let the offending line look like
foreach my $key (keys(%$param)) {
Or try to be more specific in your questions, always mentioning - what
- code stripped down to a minimum
- where
- in the code
- which results
- e.g. error messages you got
- why
- Problem you try to solve
(not necessarily in this order and on occasion deeply nested :)
Edit: fixed $% to %$
