Code works, don't know why 🤷‍♂️

'Code works, don't know why'
Been there, with VBA. Inherited a project with it's 'continue on error' flag enabled, eventually found that a value was being pulled *from another file in the same directory*. Because, you know, that'd be better than just having an absent value, right?

My first VBA project, I should add. Flag set off, forever.

if it's web, the answer is probably browsers. they are too good at running shit code
