Web Designer Upload Problems

[prmnsuper8]

I get the error: index_htm_files: Pemisssion denied. I downloaded XaReg and used debug
The following is what I got back:
[524] In background FTP thread
[524] Passive connection 0x00cc0008 made by 0x09feea44
[524] FTP thread: CREATEDIR 'index_htm_files'
[524] GetCWD
[524] FTP thread: SetCurrentDir('index_htm_files')
[524] SetCWD index_htm_files
[524] Not pending err = 0x00002ee3 12003
[524] AddError('index_htm_files: No such file or directory')
[524] FTP thread: CreateDir('index_htm_files')
[524] CreateDir index_htm_files
[524] err = 0x00002ee3 12003
[524] AddError('index_htm_files: Permission denied')
[524] FTP thread: Failed to create dir
[524] Leaving background FTP thread
Can you tell me what I need to do next to fix this?

You will need to contact your web host about the error. They will need to grant you permission to create subfolders within your web space .
