catalog client script not working in service portal

[Thomas99]

Can someone please help!

I cant get this catalog client script working in service portal, however works fine in the native UI.

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    var currentDate = new Date();

    var minStartDate = calculateMinStartDate(currentDate, 2);

    var startDateField = g_form.getControl('start_date'); // Replace 'start_date' with the actual field name

    var selectedStartDate = new Date(startDateField.value);

    if (selectedStartDate < minStartDate) {

        var message = 'Start date must be at least two business days from today';

            g_form.showErrorBox('start_date', message);

        startDateField.value = ''; // Clear the field

    }

    function calculateMinStartDate(currentDate, days) {

        // Add 'days' business days to the current date, excluding weekends

        var minDate = new Date(currentDate);

        while (days > 0) {

            minDate.setDate(minDate.getDate() + 1);

            if (minDate.getDay() !== 0 && minDate.getDay() !== 6) {

                days--;

            }

        }

        return minDate;

    }

}
