Help with vba for userforms

Hello All,

I am working on a large project, and a major part will be allowing others to add/edit data on a worksheet. I am a VBA lightweight, but have been using this forum to self teach, but I am feeling lost on the User Forms. I have created the form, and have all my fields in, but I am trying to understand what code is required to make it work. I have played with som eonline examples and can get those to work, but am unable to translate it into something that suits my project.

The idea is that they can launch the form to add or edit a job to the jobs list. In the Add tab they can add a new line ot the jobs list, in the edit tab they can enter a job and it will call up the information and allow them to edit and save the existing info. I will include a workbook that has all the data needed for the form, and have put in notes on what is what in the document. More than a solution, what I am hoping for is something with notes explaining what each part is referring to, so that I can learn how rather than just ask someone else to do it.

If you need any more details I will be eager to answer. Thanks for any help that can be provided.

Dan
