Comparison: == Assingment: = (and _not_ the other way 'round) And then... Why would you even think about comparing to fixed strings? You wouldn't. So I guess you'd like to send some real code next time, so people can see what you're trying to do. And then... "inf" = "inf" doesn't work _at all_! It produces an error. If you use "inf" == "inf" the result is exactly what you'd expect. And then... In your real code, which is something like $var = "inf", you should use $var == "inf". If you do that, you won't have any problems. -- * R&zE: *************************** ** Renze Munnik ** ** E: renze@datalink.nl ** M: +31 6 218 111 43 ***************************
