You have to put the numeric validation in the validations field in the a!formLayout(). That way the validation will always be checked, even if a specific section is hidden.

You'll need to write a rule to check if local!b is a number, usually that's done this way:
ri!variable: the string you'll be performing the numeric validation on.
len(cleanwith(ri!variable,"0123456789"))=len(ri!variable)
