Form a binary number from drop down lists
<p>So,
I have 8 drop down lists that are populated with the values 0 and 1. With the selected values from those 8 drop down lists, I want to put them together to make a binary number.
From there I'd convert the binary number to a decimal(the decimal output would be displayed in a textbox, so the decimal number would change everytime a different number in any of the drop down lists is changed).</p>

<p>But I'm unsure of how to get all 8 of the selected values combined to make an 8-bit binary number so I can convert it once I get that number. Any suggestions on how I should start this?</p>
