Java Script Drop-down option deletion but little bit different

[Aravind JAI]

I have 5 rows and 2 columns of drop down boxes.while selecting a value in the 1 column drop down,2nd column drop down should display the corresponding values.

If u choose the first value in the first drop down,then the second drop down will display the values..select one value from this..

do Like this for the second row..but select some other value in the 2nd row 2nd column drop down box..immediately check the first row 2nd drop down values..the recently selected value should not be there..

So,if one option value is selected in any of the second column that value should not be available immediately.


Please give me a suggestion
