RE: [FreeTrade] Need help with $Screen command

[Michael Puglin]

One more thing, why are you appending an empty string to the beginning of
your URL?

In the first example, 2 double-quotes together = empty string.
In the second example, the first of the double-quotes is escaped by the
backslash. This allows it to be part
of the HREF string.
