Ok, so that did work. Thank you for the help, I appreciate it. I wrote the code that way because in the documentation for Conditionals they had wrote,
"Next, we'll fill in the EXPRESSION IF TRUE part of the conditional. When #Da# == "AM" is true, we want our layer to appear, so we'll want the opacity to be 1:"
I guess the reason why I couldn't see it was because it was at 1% opacity.
Thank you again.
