Check my sig... there's a link "I swear I saved my data, where'd it run off to?" ... read, see if it's something that applies in this case. If not, let us know.

OH... I should have taken a closer look there... for starters... your insert query is incorrect...
All of your query commands aren't right as far as I can tell...

INSERT INTO Vaction (Start_Date,End_Date,Begain_Bal,Used,End_Bal) VALUES (Start_Date,End_Date,Begain_Bal,Used,End_Bal)

should be
INSERT INTO Vaction (Start_Date,End_Date,Begain_Bal,Used,End_Bal) VALUES (?,?,?,?,?)

Access doesn't use named parameters... so you have to mark your parameters with a place holder - the "?" ... and then add your parameters IN ORDER, LEFT TO RIGHT. When you add them, you can give them a name for readability, but since it's going to use positional parameters, you can basically name them anything you want.

Also, there's no point of calling the Update or AcceptChanges since you've only just filled the datatable, there are no changes to update or accept.
