Need guidance to build my app

Need guidance to build my app

Hello,

I am new in Zoho and what I'm trying to do is to build a simple app to place my customer's orders in and have my customer check my website to see the order status. 

1. I have built my form and populated it with my customers' orders.
2. I have built a view to update my customers' orders. That I will do myself.
3. I need a view that I will imbed in my web for my customers to type in their invoice number then when they click submit 
    they will then see the order status information. 

I need help and guidance on how to do number 3. 

Thanks,
Mac
