Onchange client script is not working.

[Sangeetha8]

When change request state is moved to implement state actual start date is mandatory. If actual start date is less than planned start, then throw error message and make justification field mandatory.

I have written onChange client script for actual start date.But it is not working properly,it is making  justification field  mandatory even the actual start date is not less than planned start date.please fix the issue

  var currentState = g_form.getValue('state');

    var acutalstart = g_form.getValue('actual_date');var plannedStartDate = g_form.getValue('start_date');

     if (currentState == -1){

if  (acutalstart < plannedStartDate) {

           g_form.addErrorMessage('Actual Start Date cannot be before Planned Start Date.');

            g_form.setMandatory('u_justification_end', true);

            g_form.setValue('state', '-2');

     }

        else{

            g_form.setMandatory('u_justification_end', false);

     }

}

Hello @Sangeetha8,
Try with the below script

var currentState = g_form.getValue('state');

var actualStartStr = g_form.getValue('work_start');
var plannedStartStr = g_form.getValue('start_date');

if (currentState == '-1') {
    if (actualStartStr && plannedStartStr) {
        var actualStart = new Date(actualStartStr);
        var plannedStart = new Date(plannedStartStr);

        if (actualStart < plannedStart) {
            g_form.addErrorMessage('Actual Start Date cannot be before Planned Start Date.');
            g_form.setMandatory('u_justification_end', true);
        } else {
            g_form.setMandatory('u_justification_end', false);
        }
    }
}

update as this

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    var currentState = g_form.getValue('state');
    var actualStart = g_form.getValue('work_start');
    var plannedStartDate = g_form.getValue('start_date');

    // Only trigger logic when moving to implement state (replace -1 with correct state value if needed)
    if (currentState == '-1') {
        var actualStartDateObj = new Date(actualStart);
        var plannedStartDateObj = new Date(plannedStartDate);

        // Validate that both dates are valid
        if (!isNaN(actualStartDateObj.getTime()) && !isNaN(plannedStartDateObj.getTime())) {
            if (actualStartDateObj < plannedStartDateObj) {
                g_form.addErrorMessage('Actual Start Date cannot be before Planned Start Date.');
                g_form.setMandatory('u_justification_end', true);
            } else {
                g_form.setMandatory('u_justification_end', false);
            }
        }
    }
}

I have missed one part, I need to set state value as previous state if actual start date is less than planned start date
