Hi, everybody!

I'm working with a form which displays a Data Grid like this:
=============================================
Expected Calibration Date - Consummated Calibration Date
=============================================
02/15/00
=============================================

Then I click on a button called "Add consummated date"
This button sets my DataGrid Enable and AllowUpdate properties to yes and then I fill in the date
(by the way, can I set the focus to the 2nd column at the end of this button code? I'm doing that manually for the time being. I guess that isn't a command like MyDataGrid.Columns(1).SetFocus)
But, let's going on:

Data Grid
=============================================
Expected Calibration Date - Consummated Calibration Date
=============================================
02/15/00 02/15/00
=============================================

And then I click on a button called "save", which runs the command
MyADOData.Recordset.Update
p.s. MyADOData is my datagrid DataSource.

But it causes an error message:
-2147467259 There isn't information enough about the column key to update or change the record.
MyADOData has 3 fields:
EquipmentID, ExpectedDate and Consummated Date, and I'm sure that all these columns have a value in it, cause I can see them.

So, what can the "not enough information" message be talking about?

Any ideas or comments?
Thanks in advance, folks
