I have the following functions: Public Function SaveExample() As Boolean & Private Function ValidateExample

  • 0

I have the following functions:

Public Function SaveExample() As Boolean

&

Private Function ValidateExample (ByVal vlngvariable As Long) As Boolean

I want to be able to call the second function from within the first. But I get:

“Compile error: Argument not optional”

Is what I’m trying to do possible, and if so, what is the correct syntax? I’ve simply tried adding the line:

ValidateExample

Within some of the logic of the first function.

    It looks like you should specify a value for parameter vlngvariable.

    For example, within the function SaveExample() call ValidateExample(x) where x is the value that ValidateExample is expecting.
