I'm using Sign up forms to create a "Copy/paste a form to your site" signup form.
I have a custom mobile number field that I would like to validate as a number.
I can get it to validate if there is no data entered in the field.
<label for="fieldiilthty">mobile</label><br />
<input id="fieldiilthty" name="cm-f-iililkj" type="text" required />
Is there a way to check if the data entered is a number?
Managed to get it validating using the article example.
