Need help with flags

[erick-flores]

Hello all

I am trying to build this Invoice application. I have the following
fields:
Customer Name
Invoice Date
Total
Current
31-60
61-90
90+
This is an already build table that was giving to me so I can create
this application. Basically what I need is to create an application
that will alert/tell accounting about the aging of the invoices. In
other words, if the invoice is past 31 days, a flag or pop-up message (
I dont know whats the best way) will tell accounting about it and at
the same time will display the customer information with their
respective phone number, invoice #, phone number, etc. The same
environment if the invoice is past 60 or 90 days.

Can somebody give me some ideas of where to start and what will be the
best design to accomplish what I am trying to do? I was thinking of
creating a list of all the invoices b/w 0-30 days, where accounting can
look at it and click the customer they want, once they click on it they
can see all their information. Create another list for invoices b/w
31-60 days and another for 61-90 days.

Any ideas???

Thanks in advance
