I suspect I'm probably just being as thick as the proverbial porcine excrement but....
How on earth does one get more than one variable in a text box?
For example, say I want a text box to display two custom db variables in my TV shows - Episode number and episode name :
category>tvshows>epnum category>tvshows>epname
Each on their own is fine but as soon as I type anything else in the box, the variable output disappears.
