[wp-testers] apply_filters()

[Karl Wångstedt]

Hi all

I'm trying to make a function in my parent theme fiterable (is that a  
correct description?) by apply_filters on the return value.

But now it seems like I can only add_filter() to the result if it gets  
echoed from the function. Now I'd like to just return the result for  
use in PHP, but then the add_filter() isn't applied.

Is it so, or am I doing something wrong?

Thank you
