convert number variable to text

There are multiple text input boxes on screen at once.  example, textinput 1,  with correct answers of 4, four, 4mm.  textinput 2 with correct answers of 6, six, 6mm. 

when doing the actions to to see if the imputed text is is one of those it will see 4, and 6 as not being = to the correct answers as storyline doesnt convert number to string.    it works perfectly fine for questions that do not need to have just a number as a possible answer.

And yes I could just use javascript and do it fully myself but this should be something storyline does on its own. it also will confuse newer authors as to why its not working if they have a limited understanding of how programing actually works.
