awk...sed problem

Hi guys,

I am tryingto delete or ignore columns in a large dataset using 'sed'. For example, I have the following dataset: -


As you can see, there are 10 columns here and the table that I am inserting into has 8 columns.

I want to delete the 3rd column (i.e. the 1's) and I want to delete the comma between Q and T. Finally I want to delete the comma at the end so the dataset looks as follows: -


I got a suggestion from another user to run the following command:

awk -F, '{ OFS=","; $3=""; print }' FILENAME | sed -e 's/,,//g' -e 's/,//3' -e s/.$//

However, the result i get is:


Its almost there but this time it has deleted the comma between X.XX & 043004.

Can any1 here help rectify this problem? Also, id like the output to go into another file....

Many thanks for your time!!
