Copy form text field contents to clipboard with a BUTTON

[timothy.jester]

I am creating a database for my customer base at work. What I would like to do is create a button that will copy the contents of the text field associated with it to the clipboard so that I can transfer the clients info to the system when they enter my store. The text field will consist of cell phone numbers...max numbers per customer is five but I need a button available to copy each number individually. I have been working on this for about 3 days and just can not come up with the proper solution that is needed. Thanks for your help!
