Thanks Ryan,

Ok, that wasn't the problem. I had that specified in the GridView
already. The problem was my function UpdateAllergy, this is what it
should be:
Public Function UpdateAllergy(ByVal a As Allergy) As Integer
Return AllergiesDB.UpdateAllergy(a.AllergyID, a.daycareCode,
a.AllergyEn, a.AllergyFr)
End Function

And what I had was "ByRef a As Allergy". Sheesh....for crying out
loud....I can't believe it. I didn't even notice that I changed it
for use in another area. I just wish it would have been easier to
trace the problem, like an error message that made a little more
sense.
