[SOLVED] Field $() is incorrect 'what does it mean'
I am creating (or trying to) an awk script to retrieve various data from an input file and output the data in a different format. I think it is self explanatory what I am attempting but I getting the error Field $() isincorrect when I reun it using
Code:
awk -f file.awk inputfile

Code:
 
#!/bin/awk -f
#get text between 'starting' and 'Ending'
#
BEGIN {
OFS=","
}
#'start loop here'
  /Starting/,/Ending/ {
#if the line contains 'starting'
    if ($0 ~ /starting/) {
       day=substr($0,8,3);
       month=substr($0,12,3);
       date=substr($0,16,2);
       sthour=substr($0,19,2);
       stmin=substr($0,22,2);
       stsec=substr($0,25/2);
       year=substr($0,28,4);
       number=substr($0,33,5);
    }
#if the line contains 'LN'
    if ($0 ~ /LN/) {
       depot=substr($0,58,3);
       order=substr($0,61,5);
    }
#if the line contains 'Ending'
    if ($0 ~ /Ending/) {
       endhour=substr($0,19,2);
       endmin=substr($0,22,2);
       endsec=substr($0,25/2);
    }
 }
#'leave loop here'
durhour=$endhour-$sthour;
durmin=$endmin-$stmin;
dursec=$endsec-$stsec;
END {
  print $year $month $date $sthour $stmin $stsec $endhour $endmin $endsec $durhour $durmin $dursec 
$depot $order
  }

I hope someone can explain why this may be the case.

Thanks in advance.

bp_sreformat

BP_SREFORMAT(1p)					User Contributed Perl Documentation					  BP_SREFORMAT(1p)

NAME

       bpsreformat - convert sequence formats

DESCRIPTION

       This script uses the SeqIO system that allows conversion of sequence formats either sequence data or multiple sequence alignment data.  The
       name comes from the fact that Sean Eddy's program sreformat (part of the HMMER pkg) already does this.  Sean's program tries to guess the
       input formats while in our code we currently require your to specify what the input and output formats are and if the data is from a
       multiple sequence alignment or from straight sequence files.

       Usage:

       bpsreformat -if INFORMAT -of OUTFORMAT -i FILENAME -o output.FORMAT

	 -h/--help	  Print this help

	 -if/--informat   Specify the input format

	 -of/--outformat  Specify the output format

	 -i/--input	  Specify the input file name
			  (to pass in data on STDIN use minus sign as filename)
	 -o/--output	  Specify the output file name
			  (to pass data out on STDOUT use minus sign as filename)

	 --msa		  Specify this is multiple sequence alignment data

	 --special	  Will pass on special parameters to the AlignIO/SeqIO
			  object -- most of these are for Bio::AlignIO objects
			  Comma separated list of the following
			  nointerleaved   -- for phylip,non-interleaved format
			  idlinebreak	  -- for phylip, makes it molphy format
			  percentages	  -- for clustalw, show % id per line
