Above is the code i am using to create dynamic table with item cd,item description,quantity,unit etcs
every thing here now is running fine now what i want to do is test values in item cd field.
the item cd field is unique while entering to database,on clicking the add category link its takes values from the database such that is puts the values in item code,item description,quantity etc, now i want to check the item code value so that it cannot select the same item code twice.

i dont have idea please help.

Use code tags!

There is way too much code to weed through.

What issue are you having with that validation step? Seems like you would keep an array of values that are selected and check to see if the item in in the array. If it is, throw an error.
