Hi @NiloferS ,

Please try the below:

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

    if (isLoading || newValue == '') {
        return;
    }

    var helpText = '';

    switch (newValue) {

        case 'csr':
            helpText = "Description about Business Item";
            break;

        case 'letterOfAuthority':

            helpText = "Description about the matters requiring letter of approval";

            break;

        case 'power':

            helpText = "Description about the matter requiring Power of Attorney";

            break;

        case 'board':

            helpText = "Description about the resolution ";

            break;

        default:

            helpText = "Please select a sub-category";

    }

    var descriptionField = g_form.getField('description');
    if (descriptionField) {
        descriptionField.expand_help = true;
        descriptionField.help_tag = helpText;
        descriptionField.instructions = helpText;
    }
}

Please hit like and mark my response as correct if that helps.

Probably easier to show field message under description field rather than help text. You can use g_form.showFieldMsg in your client script to show whatever message you want under description field. You can build your conditions as you did above and use this and show message accordingly.

var description_text = "Description message here";
g_form.showFieldMsg('description', description_text, 'info');
