I have received help when I asked how to add a 2nd Input Box to the freeASPupload script. Most of the help I received was in the form of modifying the code in the uploadtester.asp file. And it worked successfully.

Part of this modification included changing:

"Private Sub Upload()
to
Public Sub Upload()"

in the freeASPupload.asp file. Which I did.

My question is, can you please tell me if there are any ramifications to
changing Private Sub Upload() to Public Sub Upload() ?

Is this particular Private to Public change bad, good, or insignificant?
I guess I'm asking, is there a downside to making this particular change?

Thanks.

Nope.

Using public simply means the method can be accessed from other pages where the class is declared.

Insignificant. The downside to broadening the access modifier is that calling code will have one more method to decide amongst. That means you have to use descriptive names, like Upload, to do an upload.
