submit from only after payment to paypal

I just want to clarify if I have this right in my head.
paypal standard addon,using paypal standard account
after completing a form and clicking the submit button .. the user filling out the form,is then taken to paypal to complete the sale.....if they cancel the sale ( backout,close the browser window, what have you........the form is still submitted and can be found in the entries of the form.
is my thinking correct here?

If so ....how can we stop the entries being submiitted ?
Why would anyone want a form connected to paypal ,that adds the uncompleted entry to their database?

I have used the search function here ,and this is pretty much what I have found through reading
also after filling in my own form ,and then backing out of the payment from paypal....Ilook in the data base ...and low and behold...theres the form entry....with "payment status " ..."processing "

while we are at "payment status " in the gravity form ....is there a reason that this cannot be dragged and dropped into an "active column " for viewing from the "entries " page?

If there is a way to use paypal standard ,and have the gravity form "not submit" unless payment received..............could someone point me in the right direction please

Thanks for the reply,
I kind of figured this,and in my mind remeber reading this....stupid me let the paypal rep talk me into standard paypal...when I knew that it was pro that I needed...hopefully its a painless switch up to pro.

in my initial question................this after hitting "edit" on the entries screen....trying to drag specific columns to the main screen .....stopped trying after "payment status" wouldnt drag and drop.

while we are at "payment status " in the gravity form ....is there a reason that this cannot be dragged and dropped into an "active column " for viewing from the "entries " page?

That was the problem.......drag to top on inactive column, then drag to active column works........
