George,

>If this is the case, then I'd opt for the existing structure. The reason for this is readability. As it is the code is readable. It becomes less so using IIF().

I fully agree with you. I've been working in systems mantainace for a long while, and could learn how important readability is. Even if I have to sacrifice other aspects, I rank readability very high (constructions, choosing appropriate variable names, enforcing conventions, CamelCasing, comments, indentations etc).

Very nice to hear this!
