Format function doesn't work in ASP.NET?

[Eras3r]

Ok... I have a string that contains "1" ... I want to format it so that it will hold "00000001"

So I just do...

s1 = "1"
s2 = Format(s1, "00000000")

s2 now equals "00000000" ... when it should be "00000001"

This works in regular VB, but not ASP.NET .... WHY?!
