To access a value of a selected option in javascript you can use the following code in a javascript function that you define:

//example that pop up a message with the value of the selected value in a select boxfunction alertSelectedValue(){alert(document.forms[0].yourSelectBoxName[document.forms[0].yourSelectBoxName.selectedIndex].value);}

Hope this helps you in your algorythm

Sorry!! the correct way to access is document.forms[0].yourSelectBoxName.options[document.forms[0].yourSelectBoxName.selectedIndex].valueNote that "options" was added... I forgot to place it in my previos post... sorry.also... you can access a select element by the "document.getElementById(mySelectId)" function (if an id is defined for your select)please read this page with tutorials and properties of the select element
