FM "GUI_UPLOAD" : Error Message

Question

Dear All,
I'm doing one Customer Invoice upload program.
In the selection screen, I have one parameter to get File path from the users.
It executes first time without any error.
I dont change any parameter in the selection screen. I execute this program again. But it shows an information message stating "WRONG PARAMETER: FILE_NAME" and after OK, it shows an error message stating "File is not available". This error is coming from the FM "GUI_UPLOAD".
I set breakpoint after GUI_UPLOAD. SY-SUBRC = 1. It means "file_open_error = 1".
Can anyone tell the reason and solution for this problem?
Points will be rewarded.
Thanks & Regards,
Neeraj
