Write a Javascript codelet for my Articulate Storyline course

I am creating an e-learning course using Articulate Storyline. I want to be able to delete spaces and apostrophes from user entry fields which are auto-generated by the the software, and automatically named TextEntry1, TextEntry2 etc. I can write code that deletes these from one such text entry field, e.g.: var p = GetPlayer(); var textentry1 = [login to view URL]("TextEntry1"); var newTextentry1 = [login to view URL](/^\s+|\s+$/g, ''); [login to view URL]("TextEntry1",newTextentry1); //This takes TextEntry1, calls it textentry1, replaces spaces with '' and calls this value newTextentry1, then sets TextEntry1 to be this new value. But I need to create a loop which cycles through from 1 to n, appending the number each time to the variables TextEntry, newTextEntry and textentry. I can then set n to be the number I need for any given slide. I hope this is clear! :/
