Submit maya to dealine .mel

// Error: file: //render01/DeadlineRepository6/submission/Maya/Main/SubmitMayaToDeadline.mel line 1621: Invalid expression type for IF test condition. //

Does anyone know what this error means?..

Thanks

My research into that error shows that it was something we fixed in Deadline 6.1, so if you can upgrade to 6.2, our latest release version, it should all be good. Is that an option for you folks?
