Hi,
I guess that there is a problem the second dropdown menu to be identified or the failing step tries to access it before it becomes available.
- Please add a Wait or Wait for Object step before clicking on the second drop down menu.
- Change the Object Timeout of the problematic step. This is available via the Step section on the step's properties.
- Check if the second drop down menu is correctly identified. For additional information about Overcoming Object Identification Challenges please review "HP LoadRunner v11.00 - Ajax TruClient Tips & Tricks - Object Identification Issues" available from the following post: http://h30499.www3.hp.com/t5/LoadRunner-Support-Customer/LR-Support-Tip-Ajax-TruClient-Videos-and-knowledge-documents/td-p/6327643#.UvSdCnewbfc and LoadRunner User Guide.
Kind regards,
