The event occurs when the user clicks on the configured field, thus allowing specific actions to be performed after system user interaction.
Example:
In a Radio field, we want to hide or display another field depending on the value clicked on the radio field.
if ( {fld_radio} == 1 ) {
sc_field_display({fld_information}, on);
}else{
sc_field_display({fld_information}, off);
}
