Restrict text field by two words only

Question

Hi,

I would like restrict the user to input in a text field until 2 words, separeted by comma.

It´s possible in survey connect 123?

Eg. Car Cat = Correct (2 words and 1 space)

Car Cat Ball = Wrong (3 Words inputed)

Thank´s

A couple of ideas:

* Use a regular expression in the constraint column. For example regex(${input_text},".[,].")

* Use a custom JS function to define the logic of your text evaluation. For example, you could use split on your input text to check if the array with a comma separator has two entries

Attaching both options so you can see them in action. Start with the RegEx one. It is simpler.
