Could a Wappler Team Member Please Explain The Different Variables Available in a Flow?

Dear @George, @patrick

There appear to be 3 kinds of variable in a flow, available through:

• Assign
• Set Global
• Run => .setValue()

Could someone please explain how these work, especially with regard to:

1. Their scope, with regard to inside or outside repeats
2. If I can guarantee Run => .setValue() with operate synchronously with other statements in a flow
3. Is Set Global the same as Run => .setValue()?
4. How I can accumulate a value in a repeat and then pass its final value out again when the repeat has finished.

I could spend hours trying to work it all out, but would much prefer to just read some simple documentation on it!

Thanks in advance,
Antony.
