I used Firebug to look to see what possibly could be going on and this is what I found:

So it looks like the POST requests are taking F-O-R-E-V-E-R (meant to sound like on the movie Sandlot)! Playing around with an empty form, the post requests show each time I add a row to a table and select a To or From field. Any ideas on how to speed this up?

Hi Blake, I work for a School Board and we also also trying to create a Mileage/Expense Reimbursement process within forms to help streamline and automate the the current process. Would you be open to sharing with me in greater detail how you went about implementing this process? Any advise and guidance would be greatly appreciated! Thanks very much
