[GNC] Reversing a finished credit card reconciliation

[Gregory Donavon]

 I hope you can help me unwind an error I made after not following one of
the steps in a busybee post video on youtube: I transposed a couple of
numbers on one transaction, this resulted in there being a difference of a
few dollars. Rather than hitting "postpone," I hit "finished" with the plan
of coming back later to figure out the location of the error. When I
changed the transposed entry to the correct amount, that didn't correct the
problem because when I went back in to reconcile , the starting balance was
wrong and I could not change it or bring up the original reconciliation
page. Is there anything I can do - this is my first month using gnucash.
Any suggestions you have for reversing the transactions would be
appreciated.

Thanks for your help,
Gregory Donavon
