Hi  @snow34 

Check this:

function onChange(control, oldValue, newValue, isLoading) {
    // Exit if the form is still loading
    if (isLoading || newValue === '') {
        return;
    }

    // Split the newValue into an array (List Collector returns a comma-separated list)
    var selectedValues = newValue.split(',');

    // Iterate over the selected values and show a message if 'PROD' is found
    for (var i = 0; i < selectedValues.length; i++) {
        var value = selectedValues[i].trim(); // Trim any extra whitespace

        if (value == 'PROD') {
            // Show an info message box on the 'Environment' field
            g_form.showFieldMsg('environment', "You have selected the PROD environment.", 'info', false);
            break; // Exit loop early if 'PROD' is found
        }
    }
}
