in reply to Stumped on an array ref error...

using the last index ($#) requireds an array.
($#{$cacheHOA{$sum}} is trying to use it on a scalar, not an array. This is untested, but maybe ($#{@{$cacheHOA{$sum}}} would work.

Update Well,I'll be damned.

    Hey boo_radley

    Tried your possible fix but that gives me the EXACT same error msg.

    P.S: the last array index operation on that line comes straight from perldsc

    sigh...

    For the record, this is not correct. An arrayref can be used where an array name would otherwise appear, and thus Madams syntax is correct.
