Progster -
I've seen this before, and it is best left to TJ to explain why. I've just used the IsNull() function and moved on.
if ( IsNull( StaticVarGet( "passcount" ) ) )
StaticVarSet( "passcount", 1 );
BTW, I went ahead and finished the article off. I know you get the idea, but it may be of help to others who run into similar problems. Sorry for the long URL - gotta fix that soon -
