Retrieve many entries using awk

Hi all

I have a problem similar to someone else while getting output using awk and retrieving certain entries.

From the attached sample file of big file I have to retreive following headings in columns from each drug card as there are many drug cards..

# Drug_Target_.*_Gene_Name

# Brand_Name

# Generic_Name

# Drug_Type

# Indication

#Mechanism_ Of_ Action



Using below code, my output is a bit random and wired even though some part are correct as mehanism keep on repeating agian and again

some time starts with the next line rather than being fit in columns

Brand name keep going wrong sometime!!

I am trying to retreive

Code:
awk 'k>0 {if (a[k] && k==2) {print a[1]":"a[2]":"a[3]":"a[4]":"a[5]":"a]6]; a[1]=a[2]=a[3]=a[4]=a[5]=a[6]"";} a[k]=a[k]?a[k]","$0:$0; k=0;} /^# / {k=1;} /^# Generic/ {k=1;} /^# Brand_Name/ {k=2;}  /^# Drug_Type/ {k=3;} /^# Indication/ {k=5;} /^# Mechanism_ Of_ Action / {k=6;} END {if (a[1]) print a[1]":"a[2]":"a[3]":"a[4]":"a[5]":"a[6];}' drugbank.txt >drugbanknew.txt

Can anybody check my code in his/her system and let me know wrong things ?High thanks

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
