Extracting lines and saving - awk

Hi All,

I am trying to extract lines bsed on pattern matching../mp straight-flow/
Extracted output should be saved in meta_string , but the code is not working in that manner,saving repeated lines. can anyone please suggest where am i going wrong.

/mp straight-flow/ {
start=index($0,"straight-flow");
if ($2=="straight-flow") meta_string=(meta_string "\n" substr($0,start));
print(meta_string);

mp straight-flow Transformation_records_to_fit_COBOL_Requirement.Generate_DAG_Counts.Flow_24 Transformation_records_to_fit_CO

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
