I am discovering a whole lot of power in Text Lists, and the very first example in Help topic Text List Programming opens a new world. But I’m missing some key information to make it work for me. The first example shows how to extract a particular value from a certain column in the currently highlighted line, using the tabarray( function. The example array to be extracted from is called “destinationChoice” and is described as “the field or variable that was set up for the text list selection.” I assume this means the very first entry point in the Text List Options pane: Selected Value. I have put a variable name there, expecting it to be used as the first tabarray( argument, but my procedure that is trying to use it just returns “variable has no value”.
So 2 questions: is this the place where the tabbed array in my Text List gets its name? If not, where?
That is actually one question; my other one is: when a previously unknown variable name is entered into such a form field that is expected to contain a fileglobal variable, when does that variable become defined and given a value? Initially the error I was getting was “variable does not exist”; when I declared it in the procedure itself, the error becomes “variable has no value”, so I haven’t solved anything.
