Errors Creating a datagridview with Checkboxes

[Amanda Hartley]

I am Getting an error of
Title: DataGridView Default Error Dialog
Content: The following Exception occurred in the DataGridView:
System.Exception: Sent to Pinnacle 01/23/2012 is not a valid Value for Double. ---> System.FormatException: Input String was not in a correct Format.
at System.number.stringtoNumber(String str, NumberStyles Options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal)
There is more to this error but pretty much the same content as above over and over again.

I am basically updating my database with my results table and this routine goes back in and checks the database to ensure all fields were updated correctly with the appropriate data and checks any boxes where the results brought back are incorrect or do not match, or the row was skipped based on criteria specified on my original Query.

I apologize for the immature style of coding as I am self educated in VB.Net Programming. I am sure there are more effective ways to accomplish what I have written, but for the most part my code does exactly what I need it to do.

Thank you for any assistance you can offer!
If you need more information I would be happy to provide anything you may need to assist me.
