QS:Em validation sq

Subvraag validatie vergelijking (em_validation_sq)

Beschrijving

This is an equation that is used to validate each subquestion (text field) individually. Any text field that does not pass these validation conditions will have its background color turned pink (using the .em_sq_fn_validation CSS style) to highlight the error. Note that this is available in addition to the regular expression-based validation option.

Geldige waarden
