they are not actual field names in project.

this is the information that I am trying to report on. I am not sure what fields I need to use in project to get this info.

I want to be able to enter the estimate start and end dates and the estimate hours, and then when the task starts be able to enter the task start date, and when the task ends, enter the task end date and the hours that it took to complete the task.

I would then want to see the gant chart showing the estimate info and the actual info so that I can see how I did.

I am not sure how to get this information or what fields I need to populate to get this information.
