I tend never to use if...elseif's at all, and use switches. Like Rob said, you can fall into further cases below, and it's very simple to add more at a later date. There is one place where an if...elseif would work and a switch could not, and that is where you were performing lots of different logic tests on different variables. Aside from that, I think any speed benefit one would have over the other would be marginal. Ash www.ashleysheridan.co.uk
