Hi,

I must admit I'm a little frustrated.  I just spent two days setting up this database for my company and then I go to add my first legit record and.......FAIL.  When I fill everything in and submit, I get:

1 . [t_704788000000012742] Exception occured while setting value in PreparedStatement for the Column [Notes_704788000000021173] Check whether the datatype for this column is given as specified in the data-dictionary .[t_704788000000012742] Exception occured while setting value in PreparedStatement for the Column [Notes_704788000000021173] Check whether the datatype for this column is given as specified in the data-dictionary 

And that's after I tried importing my data with no success and no explanation.  

Grrr.

Please help!
