Text field - How to accept numbers only

I have a text field for a price in a front end item form and I do not want the user to be able to input anything except numbers.

When I add the 'Currency' Value Validation Mask, the user does not get an error if other characters are put in and when the item saves, the field is blank.

Is there a way to verify the field either as the user is inputting info or after they submit and have an error appear?

Thank you

hello did you use mask input in field ?

Per attached photo, I have the mask set to Currency, I also tried Integer, neither showed any sort of error

hi yes i
did you check any js error ? in front and backend ?

I'm only seeing this one related to Google Maps, but it hasn't seemed to affect anything else on the site

can you remove i to be sure (for exclude conflict)
