Passing a variable from Photoshop to Illustrator

Question

Alright, so I've been on here a lot the last couple weeks trying to figure out BridgeTalk, and I am starting to get the hang of it. I am writing an Illustrator script which will open a specified template and then grab Photoshop's active document and place it on the template. I have everything working perfectly with one hiccup. The script goes to Photoshop, grabs the filepath, opens the Illustrator doc, and places the file perfectly. BUT it always takes two runs through the script for it to work. It's the weirdest thing. So if I run the script when PS first opens, it gives me an error; if I run it again it works perfectly, but if I close that PS doc and open a new one, then run the script, it places the previous document!

I am stumped and have tried everything I can think of. Here is a simplified version of the part of the script that produces the error. The first time I run the script, "alert(psFile)" is completely wrong, but when I run it again it works perfectly.

#target illustrator
var psFile;
infoFromPS ();
var illTemp = File("/Users/art1/Desktop/template.ai");
    app.open(illTemp);
var doc = app.activeDocument;
function infoFromPS() {
   var bt = new BridgeTalk;
   bt.target = "photoshop";
   bt.body = "app.activeDocument.fullName;"
   bt.onResult = function(resObj) {
      var myResult = resObj.body;
      psFile = File(myResult);
}
   bt.send();
}
alert(psFile);

this simplified version is so simplified that is not connecting illustrator with photoshop in any way to be able to tell...but in any case, your script is not waiting for the result, it keeps going after you send it, that's why you get an error the first time, then after you get the previous result

it goes like this the first time

var psFile; // undefined
infoFromPS (); // I'm not waiting for bridgeTalk to fetch me the result
alert(psFile); // psFile is undefined,
//...bridgeTalk returns the result after you're done
psFile = 'some file';

second time, or after you change the ps activeDocument

var psFile; // I still have in memory the result from previous run ('some file')
infoFromPS (); // I'm still not waiting for the result
alert(psFile); // psFile is 'some file' from previous run,
//...bridgeTalk returns the result after you're done
psFile = 'some other file';
