%expand & %/$ Parameters
 
"title=%expand(%item(@TitleVar,$num))" treats "%item(@TitleVar,$num)" as a literal string rather than a function that is to be executed to get the parameter to expand. The same problem occurs when using local variables. It seems that it will only take @variables or else will treat as a literal string, which means it takes 4 lines of code bouncing between variables to execute what should only take one.

While there may be a problem with %expand, in most cases you don't need to use it. If we could see the whole of your code, we could suggest a better way.

Timed trigger *180
Code:
title=%item(@TitleVar,%random(1, %numitems(%expand(@TitleVar))))
title %expand(@title)

@title is a placeholder variable, useless except to get around the bug.
@titlevar is a string list of titles, some of which contain references to other variables, thus the need for expansion.

Assuming everything worked right, this could be written as a single line of nested function calls, but this was the only way I found to get the functionality I wanted (though I can break it up furthur into more easily readable lines but it is now more compact than it was when I posted.).

Code:
%stripq(%item(@TitleVar,%random(1, %numitems(%expand(@TitleVar)))) )
