problem with reference archive path

Hi
Thanks for this great script - has saved me a lot of time. I have just  
one minor problem when automating a differential backup via cron. When  
the script is run it is giving the following prompt

Warning, 09-15-2008_1004.10.dar seems more to be a slice name than a  
base name. Do you want to replace it by 09-15-2008_1004 ? [return = OK  
| Esc = cancel]

so, the cron fails as no answer is given. Can the script be altered so  
it strips the .10.dar of the reference archive name so as to avoid  
this prompt? I am running it on ubuntu 8.04

Thanks
Glen
