Testing a number

Hi,

How can we test if the content of a variable is numerical?

I occasionally get an error message, as sometime the variable I pass to an arithmetic function contains a string instead of a number.

Or you can try this:

[code]
VBSTART
VBEND

VBEval>IsNumeric("hello"),result
MessageModal>Is "hello" numeric ? %result%

VBEval>IsNumeric("55.7"),result
MessageModal>Is "55.7" numeric ? %result%

[/code]
