    copied!<p>Yesterday or the day before I got some help with <a href="https://stackoverflow.com/q/7793856/115845">a drop down select to variable value match</a>.</p> <p>What happens is that if there is a match on the drop down, they jQuery code goes through the values and checks to see if there is a match on prices and cases. If there is a mismatch then the alert box is triggered. </p> <p>The first part works fine, but the second part is more tricky and I can't seem to figure it out.</p> <pre><code>$("select").change(function() { var $this = $(this); //first part if ($("select").filter(function() { return $(this).val() === $this.val();}) .parent() .next() .children("input[value!='" + $this .parent() .next() .children("input") .val() + "']") .length != 0) { // alert alert('mismatch1'); } //second part if ($("select").filter(function() { return $(this).val() === $this.val();}) .children("td:eq(2)::has(input[value!='" + $this.children("td:eq(2)&gt;input").val() + "'])").length != 0) { // alert alert('mismatch2'); } }); //$this.children("td:eq(2)&gt;input").val() &lt;&lt;&lt; this works &lt;form name="form1" ID="form1" action="array_script.cfm"&gt; &lt;table id="test1"&gt; &lt;tr&gt; &lt;td&gt; &lt;select name="selectA" id="selectA" class="priceA"&gt; &lt;option id="A" value=""&gt;None&lt;/option&gt; &lt;option id="A" value="A"&gt;A&lt;/option&gt; &lt;option id="A" value="B"&gt;B&lt;/option&gt; &lt;option id="A" value="C"&gt;C&lt;/option&gt; &lt;/select&gt; &lt;/td&gt; &lt;td&gt; &lt;input id="priceA" type="text" name="price" value="8.99"&gt; &lt;/td&gt; &lt;td&gt; &lt;input id="perCaseA" type="text" name="perCase" value="4"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; &lt;select name="selectB" id="selectB" class="priceB"&gt; &lt;option id="B" value=""&gt;None&lt;/option&gt; &lt;option id="B" value="A"&gt;A&lt;/option&gt; &lt;option id="B" value="B"&gt;B&lt;/option&gt; &lt;option id="B" value="C"&gt;C&lt;/option&gt; &lt;/select&gt; &lt;/td&gt; &lt;td&gt; &lt;input id="priceB" type="text" name="price" value="8.99"&gt; &lt;/td&gt; &lt;td&gt; &lt;input id="perCaseB" type="text" name="perCase" value="4"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; &lt;select name="selectC" id="selectC" class="priceC"&gt; &lt;option id="C" value=""&gt;None&lt;/option&gt; &lt;option id="C" value="A"&gt;A&lt;/option&gt; &lt;option id="C" value="B"&gt;B&lt;/option&gt; &lt;option id="C" value="C"&gt;C&lt;/option&gt; &lt;/select&gt; &lt;/td&gt; &lt;td&gt; &lt;input id="priceC" type="text" name="price" value="8.99"&gt; &lt;/td&gt; &lt;td&gt; &lt;input id="perCaseC" type="text" name="perCase" value="4"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; </code></pre>
