The parameterized query '(@Guru nvarchar(4000),@Mapel nvarchar(7),@ki3 float,@ki4 float,@' expects the parameter '@Guru', which was not supplied

Hi friend..
i wanna ask about myproblem like this :

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

please tell me a solution ?

You have a parametrised query ([probably using sp_ExecuteSQL) which defines the "@Guru" parameter and then does not provide a value for it.

If you can find where that is in the code (or the exception stack trace perhaps?) and post it here folk can help with the correct syntax

Post your SQL
