Re: value "" cannot convert to number

[Sam Fisher]

Thanks very much everyone.  I discovered that my routine for assessing the ID value needed an AND instead of an OR, so my empty string was sneaking through the "if" barricade.  It seems temporarily subdued, so I'll let sleeping dogs lie.  If it poses a problem again, I'll be sure to let you all know.

  You've not included what you think the value of "ID" is, but if it's "" (an
  empty string as the error indicates), then val() will return a zero - as it
  does with any non-numeric value.  Also, if it's an empty string, your math
  operations *should* fail with the error you are giving as it's not a number
  and math cannot be performed on it!

  ID should be a number if you are planning on doing any math to it.

  Subject: value "" cannot convert to number

  Hi Everyone,
        Can someone tell be why I get a string convert error.  I have tried
  setting up ID to Val(ID) and even IncrementValue(Val(ID)), but all it ever
  returns is either 0 or 1, respectively.  Apparently ID is not getting
  converted.  "I feel like I'm taking crazy pills!"  What is wrong with
  converting a string to a number, especially when the string is just a
  concatenation of numbers?

        Many thanks,
        Sam

        The value "" cannot be converted to a number

        156 : <CFSET ID=ID + 1>
