Error 1004 with save button

Hello first post so hope all my formatting is correct!
I've wrote a save button for a datasheet, the file saves but I get this error when it saves "error 1004 detected. Reason: Method 'SaveAs' of object '_Workbook' failed". The saved file gives me this error when it's opened "Cannot open file format/extension not valid verify the file has not been corrupted & that file extension matches the format of the file"

I am using a .ini file to specify the save path and this code has worked perfectly with another path so I'm at a bit of a loss as to how to correct this error.

Thanks in advance.

Thank you for your reply.

The path name is valid, the files save to the folder but appear to be corrupted/invalid when I try to open them. Unfortunately I don't want to alter the code too much as it has worked previously just with a different file path, the errors only started when the path changed.

Yes the filename forms correctly, I even played around with

as I read this can sometimes cause the error.

They all refer to the same worksheet, it is just one worksheet.
