Ok everyone. I appreciate your time if you are looking at this, as
this site is being setup to assist veterans who are having trouble
with the health care system through the VA. And as I said, we are
pretty close at this point to going live beta so if you can help me
over this hump it would be extremely appreciated.
We have a form setup that asks the user to select a date when
treatment began and then when treatment ended. After that they fill
out a free text field explaining what kind of problems they
experienced during their treatment. Then they submit it.
After that you go to user stories to view the stories submitted by
everyone. Except we are getting an error when we try to open this page
The error is posted below, and also the code from the models and
controllers and rhtml files. I REALLY would appreciate any help in
resolving this, so that I can put it into open beta, and then get it
out to hopefully help make the nation aware of what is going on within
the VA healthcare system.
Thank you for your time,
Dave
P.S. if you spot the problem could you provide easy to understand
steps to resolve it?
