yellow warning triangles in macros

[MarkGardner]

In my macros, when I use "OpenReport" I get these yellow warning triangles. I know that I am doing something wrong, but can't for the life of me figure it out and track them down. I have searched and searched and cannot find anything in any of the books nor helps. They seem to function without any problems, but I don't like to have potential landmines in my macros.

Additional information...
The warning flag goes away when I change the argument "view" from "Print" to "Report". Is that worthy of a warning flag? The problem is that I cannot find anything on "warning flags" and what they mean or if they are things to worry about.
