Benoit, The IsXXX functions confused me because when testing IsNumber("123") I got an error similar to "Expected number got a string". It seems you needed to know the type before testing for it. I therefore do not use it. However I believe new versions of software should be backward compatible so I suggest giving the new functions a slightly different name. EG: IsNumeric.
