how to create a form attached to a table

Hello,
Once again I am looking for your precious help,
What I am looking to do is having an easy way to create an event, looking for the details of it and edit info as we getting ready to it.
I attached an excel file to give you a clear idea of what I am looking to do. (this is mostly what i would like it to looks like)
This is just part of it and more info will be included but I just need to get to learn how to do it.

My sheet is compose in 3 part.
A Table with all the event and info.
A edit and new event form to edit the info in the table and create new one
A little event calendar on the left.

I may be to demanding but I learned that everything is possible on excel.
Can you help me?
Thank you in advance.

Hi remyte

What you describe is a major project...have you considered using Excel's built in Data Entry Form?

There's also a very flexible example of a Data Base Form free for download that you could adapt to your requirements here...

What you've presented does not give us much to build on...have you tried to develop your Data Entry Form (User Form)? If so, please show us what you have developed...one of us will be happy to help you through it.
