Inside of the form there are two fields called "Rows" and "Slides Per Row" that ideally was to use numbers on this, but the point is that the editors can put any string on these and save without any message or validation
Open the form
Go to fields "Rows" and "Slides Per Row"
Fill with strings and special chars
Save
Result: don't have a validation and the user can save
Expected: Since the field should be numerical we shouldn't allow save non-numerical values
Use the fieldtype of FormAPI as number to allow only numbers
