Cut Command error cut: Bad range

Hi
Can anyone what I am doing wrong while using cut command.

Code:

for f in *.log
  do
    logfilename=$f
    Log "Log file Name: $logfilename"
    logfile1=`basename $logfilename .log`
    flength=${#logfile1}
    Log "file length $flength"
    from_length=$(($flength - 15))
    Log "from length $from_length"
    logfile_date=`echo $logfile1 | cut -c ${from_length}-8`
    Log "Logfile date with stringlength $logfile_date"
done

Getting error in cut command for a file as
INT_put_daily_stock_tax_to_ML_20110520_002258
I want use cut command.

The error is showing

Code:

+ + echo INT_put_daily_stock_tax_to_ML_20110520_002258

mb_strcut

MB_STRCUT(3)								 1							      MB_STRCUT(3)

mb_strcut - Get part of string

SYNOPSIS

       string mb_strcut (string  $str, int  $start, [int  $length = NULL], [string  $encoding = mb_internal_encoding()])

DESCRIPTION

       mb_strcut(3) extracts a substring from a string similarly to mb_substr(3), but operates on bytes instead of characters. If the cut position
       happens to be between two bytes of a multi-byte character, the cut is performed starting from the first byte of	that  character.  This	is
       also  the  difference  to  the  substr(3) function, which would simply cut the string between the bytes and thus result in a malformed byte
       sequence.

PARAMETERS

	      o $str
		- The string being cut.

	      o $start
		- Starting position in bytes.

	      o $length
		- Length in bytes. If omitted or NULL is passed, extract all bytes to the end of the string.

	      o $encoding
		-The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.

RETURN VALUES

       mb_strcut(3) returns the portion of $str specified by the $start and $length parameters.

       mb_substr(3), mb_internal_encoding(3).
