[marioroy]: why do some posters not know to provide a good SSCCE? Nested loops?
[Corion]: marioroy: Producing good SSCCE is an acquired skill :) You have to produce bad SSCCEs for a long time until you get good. And when you get good, you don't need them that much anymore because you simply isolate the problem and then solve it ;)
[marioroy]: ... and kcott is able to provide something. Amazing.
