How to unscramble a list of words using a HashMap? <p>Basically I will be given two large input files.

Classic ASP FormatPercent ignores 100%? <p>The code below works out percentages for my data. All works fine apart from 100% which should be red (#B20000) but in fact is green (#32CD32). I added an option that specifically refers to 100% but even that has not effect. Any ideas? Thanks </p>
