Assigning value to SSIS variable in script task...

Hi,

I want to update a table entry using the value of the SSIS variable. The variable needs to get updated when the package fails.it should go to the exception handler. there i have a script task for exception handling and that script is connected to a execute sql task where the procedure for updation is been called. The problem is i want to update the value inside the script and pass it to the procedure in the execute sql task. How the variable can be updated???

Please suggest....

Thanks
