Make a text field (or image) in Wix forms display conditionally

[RynoB]

Here is my code so far…

$w . onReady ( function () {
});

export function radioGroup4_change ( event ) {
if ( $w ( ‘#radioGroup4’ ). value === ‘YES’ ) {
$w ( ‘#text42’ ). show ();
} else {
if ( $w ( ‘#radioGroup4’ ). value === ‘NO’ ) {
$w ( ‘#text42’ ). hide ();
