I have received some great advice on this site so far so I am going to take a different approach when asking my questions.
I have a document that is created by users with a number of days and date range. I would like the form to create some kind of way of recording activity codes per hour they have worked. My first idea was to use a combo box based on how many days the users enters and then this gives the user the chance to select the criteria (code).
Before I start looking into this I thought it would be worth asking if there was a better way of compiling this.
