Re: Multiple multiple selects

Steff, What is $$arrayName supposed to accomplish code-wise? As a variable variable named 'arrayName' what value of $arrayName[ ] do you expect to be referring to? What I'm suggesting is to deconstruct the compressed notation you are using and obviate your logic more clearly. You're on the edge of crypto-perlisms here and jamming harder into it is not likely to make it clearer. Strip it down, lay out the guts, type a lot more clear simple stupid code and see what shows up in broad daylight. I always try to take three small steps rather than voluntarily build up arrays of variable variables ...
