Converting a number variable to a text variable

Hi Everyone,

I'm creating an on-boarding module where learners have to select their department from a visual organizer. The buttons assign a value to a number variable. This is then used to direct learners to specialised scenes that cover information from the perspective of their department. This is done through adding a trigger that says jump to scene X when user clicks button 1 if department variable is X / jump to scene Y when user clicks button 1 if department variable is Y.

However, I want to have some responsive text that uses the name of the department they selected. So what I am trying to do is this:

click button -> assign value to number variable -> insert text into responsive speech bubble

in other words

click IT button -> assign "6" to department variable -> insert "IT" into responsive text.

The reason I have not used a text variable is that I want to remove the chance that the learner will enter a typo. If a typo occurs then my trigger to jump to a scene will break and the learner will be stuck.

Does anyone have any suggestions?
