Default stored procedure: time format/mismatch problem.

Hi everyone,

 I urgently need your help with the stored procedure. I intend to read in a number of values (time and day format), format it to the uk standard and then pass on.
Through the code below I carry submission date and current date as strings and then attempt to insert into the DB in relevant fields (that are datetime format, the us style).

I am getting the following error that is very straightforward, however I cant put my head ot it. Further comlication is my relative uneasy with the us/uk date format struggle.
Please, feel free to suggest constructive solutions.

--------------------------------------------------------------------------------------------------
Server Error in '/GT' Application.
String was not recognized as a valid DateTime.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Line 73: lblOrderID.Text = CStr(Session("RequestID"))
Line 74: cnn.Close()
