Eyeball this table in table design and see if the column is defined NOT NULL, and if so you'll need to change it to allow NULLs.

Right-click on table > Script Table As ... > Create To > New Query Window Editor..

-- Change the column definition to allow NULLs
ALTER TABLE YourTableName
ALTER COLUMN PickUpTime datetime NULL

Open in new window


>Datetime column
>CAST(@PickUpTime  AS  nvarchar(20)) end ,  
So which is it ... a datetime column or a nvarchar(20)) column?  Storing date values in a varchar column is a poor programming practice as it will allow all sorts of values that are not convertable to dates, which will throw an error.
