Text Entry - Freeform Pick One - trouble with complex triggers

This is quite complex and trickier to set up than you'd think, but it is possible. 

For an ELH Challenge demo I created this text input interaction that has more than one possible answer - in this case British English or American English spelling.

I've highlighted some of the pitfalls I encountered and workarounds I came up with in the above blog.  It's not quite the same as what you're seeking to do here, but follows some of the same logic.

Would be happy to discuss this in more detail with you directly.

Hi, Amy. I think the issue is with the complex And/Or logic on your conditions.

I suggest trying to add additional triggers/variables to standardize the format of what is submitted to avoid the "OR" branching in the logic. The basic idea is you'll have to have just one "correct" formatting for the answers.

Set TextEntry to variable CorrectAnswer; When TextEntry changes; if TextEntry = value *other correct format*

See the attached image for what I changed and let me know if you have any questions.

I’ve rebuilt this using your png but haven’t put in a free form question, simply using a button and triggers and it works fine. 

I can email you the SL file if you like?

Oh! Interesting to use javascript as a solution and I agree with all the above :-) 

Depending on the problem, I've found using variables with multiple triggers works as well. 

I would create two T/F variables and 3 separate triggers - one for each of the response boxes to change a T/F variable to true when the correct response is entered (EntryDiaOD_1 looses focus) and then a third trigger to change the state to "correct" when the user clicks submit given the condition if both T/F variables are "true."

This will also allow you to tailor the feedback to the learner's response if they are partially correct- IE if they enter OD_1 correctly but OD_2 is incorrect, you could add an option to show a state of "almost" or show a tool tip about what to change.

It looks like the trigger wizard is showing the level or order of the "and" statement for the "Won't work" image as paired with ".0081" instead of ("0.0081 or ".0081") and ("0.0051" or ".0051"). I'd be interested to see if this is the cause of the issue and if this can be remedied using Javascript.  

Yes it's the and which is causing the problem. You can either change to numeric entry rather than text entry. Or you can create two different triggers which checks the answer for the two numbers and sees if it is true and then check those variables instead.
