[SOLVED]The ERROR for loading two model .json files

Hi, in my project, I need to load two .json files in the order. When I have loaded second file, the model is visual in the scene, but I cannot get it by , the error is "print.js:73 B4W ERROR: get object 02_01walk: not found".
But when I loaded the file first, the code is successful.

So , how to load multiple model .json files for different times.

If you attach your JS code, I can have a look at it. Maybe you can make a comment in your code like //first object to load. //second object to load.
