Word Package Issue

I’m facing an issue while opening a .docx file using the Word package in Automation Anywhere.
When I assign the file path through a string variable or file-type variable, the document does not open.
However, if I provide the same path directly in the File Location field, the file opens without any issue.

Could you please help me understand why the path works when entered directly, but not when passed through a variable?. Then tell me how do I need to provide a dynamic path.

Thanks,
Dinesh
