saving a copy of a form

hi 

i have created a form to use with work,

i need a master copy to open, fill form in and then save it as customers name, then open form and all feilds blank again ready to be used again,

i cant seem to do this in my ipad that i use all that seems to happen is it overwrittes the main copy and i have to empty it all and refill it with new data.

i hope some one can help im even looking at having an app created for this reason.
