csv file - adding total to a trailer record

Hi,

I have a script which creates and modifies a csv file.

I have managed to do everything I need to do apart from 1 thing. I need to append a trailer record to the file. I need this line to hold the total of an entire column of the csv file (skipping the 1st line which is a header).

Can someone help, i had assumed the for loop would do the job but I am unsure how to specify the 3rd column and how to skip the first line.

Thanks

basically:

Input -
Code:
header record
detail record, 100, todays date
detail record, 100, todays date
detail record, 50, todays date

Output
Code:
header record
detail record, 100, todays date
detail record, 100, todays date
detail record, 50, todays date
trailer record, 250

# 2  
For the trailer record:
Code:
$ awk '{s+=$3}END{print "trailer record, "s}' infile
trailer record, 250
