Comparing the values of one Combo box with another combo box value and grayed out if it is same
<p>I have two combo box. </p>

<p>First Combo box ("Comb1") is having the following values.</p>

<p>Select,Test1,Test2,Test3,Test4</p>

<p>Second Combo box ("Comb2") is having the following values.</p>

<p>Test1,Test3</p>

<p>Through Javascript, I want to take each value of Comb2 and compare with the value of Comb1 and if it is same, the corresponding value of Comb1, should be grayout ( or non selectable). So, in this case, Test1 and Test 3 of the COmb1 should be grayed out.</p>

<p>Kindly help me out,as I am stuck to this point.
Thanks</p>
