I am sorry I didn't give enough information, but it is not something I do every day.
I was messing around with the GUI and buttons.
I had problems with them and after working out how to use the buttons, I wrote the calculator FLOW to share with people.
It is a basic calculator with the 0 - 9 buttons, basic maths buttons (+ - * / and =).
And a result box/display.
There is also a CLEAR and CLEAR ALL button.
To me that is confusing, but I have to "dance to the music playing" if I want to be accepted.
I wrote out a fairly detailed description on how to use the flow and what it did/doesn't do.
It was accepted - or so I thought. I didn't really keep tabs on it. It went in and there were no errors reported to me, so "it worked".
To upload it I went to the FLOWS button (top right of the page. Just beside the github button) and clicked on the "Add a flow" button and went though the motions put to me.
That sent me to github.
To submit flows github is required - from what I see/saw.
So I had to make a github login, and upload it via it.
As stated, there were no errors reported back to me at the time, so I didn't think it "failed".
But it isn't there.
It was a while back now. I can't even guess at a date so I won't pretend to offer one.
Is that any clearer?
WRT point 3:
I don't get what you mean. It is not a "backed up flow" but more one I wrote and wanted to share in the library.
Sorry I can't be any clearer. But I am telling you what I know/remember.
