Text entry interaction with decimal places

Hello there,

I have one problem with Storyline and I am looking for help.

I created an interaction in which the user is asked how much voltage is accepted in one piece of equipment.

At first, I had integer numbers with no decimals. So, for example, "12". But if the user enters, say, "12.6", it would be technically correct, but Storyline is not able to do this natively.

I can't add 12.1, 12.2, 12.n because Storyline only allows 10 options. The correct answer in this case goes from 10 to 13, so I'd need many more slots than 10. And there is also the problem that some people will use the dot and others the comma.

I have also looked in the E-learning Heroes community for workarounds and/or JavaScript snippets, but haven't found anything that is really similar to my case.

I know I can instruct users in the question stem to use only whole numbers and avoid decimal places, but I thought I would ask the community, just in case anyone had managed to tame Storyline's ridiculously limited functionality.

Thank you!
