Restrict text field by two words only

[SoratoMarques]

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. 

If not familiar with custom JS, check this: https://community.esri.com/t5/arcgis-survey123-blog/extending-survey123-smart-forms-with-custom-js/b...
