Hello @ravitejak 

Hope you are doing well!

First thing is, you can use the Dependent Value functionality to achieve this requirement. If you are using OnChange client script and it giving error then please share here. 

Below is my sample script in which I have created Category and Subcategory fields and written the onchange client script with addOption() and removeOption() methods. You can customize the script as per your field data:

OnChange Client Script:

Type: Onchange

Field Name: Category

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
		g_form.removeOption('u_subcategory', 'Chrome', 'Chrome');
        g_form.removeOption('u_subcategory', 'iTune', 'iTune');
		g_form.removeOption('u_subcategory', 'USB', 'USB');
        g_form.removeOption('u_subcategory', 'Mouse', 'Mouse');
        return;
    }
	//alert(newValue);
    if (newValue == 'Software') {

        g_form.addOption('u_subcategory', 'Chrome', 'Chrome');
        g_form.addOption('u_subcategory', 'iTune', 'iTune');

        g_form.removeOption('u_subcategory', 'USB', 'USB');
        g_form.removeOption('u_subcategory', 'Mouse', 'Mouse');

    } else if (newValue == 'Hardware') {
        g_form.addOption('u_subcategory', 'USB', 'USB');
        g_form.addOption('u_subcategory', 'Mouse', 'Mouse');

        g_form.removeOption('u_subcategory', 'Chrome', 'Chrome');
        g_form.removeOption('u_subcategory', 'iTune', 'iTune');

    }

}

Please let me know in case you need help with this requirement 

Thank you!
