    I am using the log function to calculate a field on my form and I am getting the following error when I am trying to find the log of a number less than 1 ( a negative number):

    Error Type:
    Microsoft VBScript runtime (0x800A0005)
    Invalid procedure call or argument: 'log'

    How can this be resolved.

    If you do "log(ANegativeNumber)" you can not solve, bc log is not defined for numbers <= 0

    log(0,10) = y means 10^y=0 -> err
    log(-1,10)=y means 10^y=-1 -> err
    log(1,10)=y means 10^y=0 -> y=0 !
