'Public' seems not to work from a module.

Thanks Niya, With any luck 'Visual Basic .NET for complete beginners' from Home and Learn, as recommended by this forum will get to there eventually :)
And as you can see I've carried this thread over from a previous one for the sake of relevance.

I think you know the reason I've gone back to square one. This tutorial has some bits that sadly don't actually work, and it would seem, some bits that are frowned upon by some of the gurus in here, but I'm ploughing on... I try to figure things out for myself but occasionally have to ask for help.

This is one such, I'm trying to understand 'Standard Modules', these are new to me, or at least too far back in the dim and distant past.
This tutorial says to open a Module, give it a name, and add a private subroutine. Then, going back to the Form1, add a button and in it's 'Click Handler' call the sub' in the module and we're to discover that it isn't found because it was declared as Private, all we have to do is change the 'Private' to Public' and all will be well... Ok, I can understand that... shame my project doesn't!

I changed the sub' to public but my Form1 code still can't find it. I deleted the whole project and re-did it from scratch except, this time I made the sub' public from the start, just in case... It still can't be found. :(

I'm using VS2010 with (I think) VB.NET4.5. I'm definitely not new to subroutines and functions and I'm certain I've not made any errors in the code so, here's where I need some help again.

Poppa.
