can not update more than 1 row at a time

my client side dataprocessor set up is as follows:

var dp = new dataProcessor(“getSQLDatav10.asp”);
dp.setTransactionMode(“POST”, true);

i have a button to send the data on the client side

if I update one row at a time it works fine.

if I try to update more than one row then the rows get marked (bolded) that they are to be updated but nothing happens when I send data.

My guess is that I am not parsing the data correctly when it receives the info from the grid and therefore does not return the proper response to the grid.

any help will be greatly appreciated.
