Hello everyone,
I have a goal to modify the text that displays when a user keys in non-numeric values within a numeric-only type of field. Within various TWIGs I see the following type of directional text:

- The validation message, eg: "Only numbers may be entered in this field.". This text is inside EM Helper, and can be changed by creating a translation file
- The easiest way to change the text in the warnings is to create a new translation.

In previous surveys, I've easily modified the content in the DOM using JS.
In other surveys, I've modified the core PHP files (which I'd like to avoid).

Currently, I'd like to see if there is a different method using some other area that I've yet to find. I searched in various places for "EM Helper", "Translation File", "Validation Message", etc and am not finding anything. 

Thanks for your help!
 

1: hide the default in custom.css : 2. Set validation to 3. Use your own string in validation tip1: hide the default in custom.css :
