Instead o fletting medialab replace the texts, I created multiple htms and put there directly the text I wanted.

In other words replace "question" with your specific question, "option1" with your left anchor" and "option3" for your right anchor. Do this for all the scales you need, creating a seperate htm file for each. Then direct medialab to the appropriate htm.

It would be nice if Jarvis told us how to solve the problem using only 1 htm though
