Using static variables to share data like this is usually a result of bad design. Each form is an instance of an object so you should hold data in public properties of the forms instead.

As for your actual question, this is to do with namespaces and is one of the most basic aspects of .net. If you don't understand namespaces then you're going to struggle doing any effective coding in .net. I suggest you get a book on c# and go through it to get an understanding of the basics before you tackle your project.

But the problem is that, there in no error in other windows form. In other windows form it is working without the OTS namespace, but not working in product form.

Google for articles on namespaces and how they work. You can't expect us to explain every aspect of development to you in a serious of forum posts. This stuff is extensively documented.

Typically, if a form needs some piece of data, you pass that data to the form in either it's constructor, some properties the new form exposes, or some method on that form. It should NEVER have to beg another form or class for the data it needs.

You're current model does that. It's not up to the new form to go looking around the app for the data it needs. That data should be handed to it by whatever code is instantiating the new form.
