#1
I am building up a large workbook for keeping track of a festivals finances. Currently I have a page with outstanding invoices listed one after the other. There is a set amount of rows that should be sufficient for the whole month.

I would like to have a push button placed at the top of the sheet labeled 'Add new invoice', that once clicked will activate a sort of data form style analogue box for entering the necessary data on the worksheet.

#2
I would like to have a push button at the end of each row marked 'paid', which once clicked would export the data to another page. Where the data was I would like the list of data to be moved up, so that there are no gaps in the worksheet, rather than merely delete the row, which would eventually leave no more space for new invoices (unless there is a way of setting up #1 so that we start with a blank document and the form adds a new row every time), and it would delete the 'Paid' button.

If anyone can solve this it would help out a lot.
