Goodday ,

I have created an object in a private class and want to access that object in that classes function. It would seem that it is not working.

When I answer yes to manufacturer the output is missing name, email and product supplier. If I say no then product supplier is still missing.

Enter Product_Name:
test product
Enter Product_Price:
333
Enter Supplier_Name:
shops
Enter Supplier_Email:
email.com
Is the supplier a manufacturer (Y/N) :
y

Vendor name:
Vendor email:
Product Name: test product
Product Price: R333
Product Supplier:
Press <RETURN> to close this window...

Here is my code as I am not sure why I am getting this issue.

Thanks for the help
