Can someone please tell me the script to change a specific string of characters in the middle of a filename, to a 3-character numeric sequence?

Also, on a somewhat related topic, I am using the script $num(%\_counter%,3) to append a numeric sequence to file titles.. is there a way I can force this to start at a specific count instead of the default of 001?

Thanks,  
Paul

You can use an action Replace or Replace with regular expressions for that. The format string/regular expression depends on the part you want to replace

$num($add(%\_counter%,),3)
