When you debug, and that line is highlighted as in your picture, what's showing in the Value column of the Locals pane of the VBE for LBRS?
If it's not showing Nothing or Empty, then in the Immediate pane, type:
?LBRS.address
and press Enter. What's the result?


It would be easier to help you if you could provide a file where this error occurs - sure, desensitize the file and remove unnecessary sheets/code, but do ensure that the error still occurs before posting it here.
