Modify lmstext data in data.js file

Hi everyone,

I developed a web app (installed inside the course as a web object) that extracting data from an excel sheet bank and sending it randomly into storyline pick-one interaction with player-variables positioned inside text boxes. The problem is when the interaction is being submitted into our LMS, the storyline sends the cmi.interaction data as %variable_name% instead of sending its content.

Does anyone have a suggestion for this issue? I need a workaround or something.
