Copy row if value in column L = unpaid

Hello,

I am completely lost with using macros. I can't seem to find a beginners guide for using macros on a mac. I've read several threads that solve this problem for other people (e.g. http://ccm.net/faq/4668-copy-rows-based-on-a-condition#q=Copy+rows+by+column+match+condition&cur=3&url=%2F), but without a basic knowledge of macros, this is beyond me.

Here is what I am trying to do. I have a spreadsheet listing customer transactions with column L being Payment Date. I would like to automatically copy any rows with Payment Date equaling "unpaid" to a new worksheet so that my secretary can go to the dashboard and see a list of sales that need her to process payment.

I could probably use the solution from the other thread and try to enter my own values, if someone could tell me the beginning steps to getting the macro started.

Perhaps this seems silly to try when I do not have experience with macros. Could someone recommend an online guide that will help?

Thank you!
