Storing result in last column of each row using a formulae
<p>SIRS,
i am new to jquery, but need to do on-line calculations urgently for a project.  hence please forgive me and guide me.</p>

<p>my problem is as follows.
i am displaying a html page made up of say 20 rows, each containing 7 columns.
in each row, the first three columns contain textual data.  in the fourth column  the user has to input a numeric value.  the fifth column should automatically display a numeric value (representing discount ), the sixth column should automatically display a numeric value (representing freight) and the seventh column should display a numeric value which is equal to (column 4 - column 5 - column 6).  the discount and freight values are dependent on the value in column 4.  if the value in column 4 is less than 1000, they are 0 and 10 respectively.  if the alue in column 4 is equal to or above 1000, they are 10 and 5 respectively.</p>

<p>please help me to solve the above problem using jquery.</p>
