The Custom Macro Stopped report from rendering

[alinawab]

Dear Friends,
I am facing an issue The Custom Macro Stopped report from rendering. I have report which is having two sub reports inside. The report is opening in the report view properly but when the ExportWithFormating macro runs, it throws this error thingy. Any Suggestions, please let me know. Thanking you in anticipation.
