Thanks fore replying, CarlFink. Apologies if I did not make myself clear. I am developing a Lectora template for developers that would allow them to simply enter their content in the Variable pane and publish for end users. This is not for end users. This is for developers only. I want to know if there is an option wherein developers can change the audio by using variables. For instance, if developers can define a variable and go to the Variable Manager and specify the name of audio file to be loaded at start, and they are good to go. I am attaching my source file as well. Let me know if that’s possible. Thanks in advance.
