Hi sir,
I am interested in your project and offer my services.
I am a skilled Excel, VBA developer and can provide you best solution according to your requirements.
As I understood from your description that you need a popup form that appear when you open a specific excel file and provide option to enter/select user name and password. And every user has specific rights that they can do to data, am I correct?
I'll need more details to understand whole project, feel free to contact me for further details.
Looking forward,
Nblsoft
