This is the script we used. First we placed this in the HEAD:
<![CDATA[
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
var bFirstValue = true
var bSecondValue = false
var bThirdValue = true
var bFourthValue = false
var bCheck1 = bFirstValue && bSecondValue
var bCheck2 = bFirstValue || bThirdValue
var bCheck3 = bSecondValue || bFourthValue
//-->
</SCRIPT>
]]>
Then we created these buttons:
<![CDATA[
<form>
<input type="button" name="VariableButton" value="true + false" onclick="alert(bCheck1)"><br>
<input type="button" name="VariableButton" value="true + true" onclick="alert(bCheck2)"><br>
<input type="button" name="VariableButton" value="false + false" onclick="alert(bCheck3)"><br>
</form>
]]>
