I had the same problem as bondiblueos9. Some users reported that the items did not show for a condition with a dropdown menu. Changing .onclick to .onchange solved this problem. The problem seems to be specific to chrome on a mac. There is no problem when using safari on a mac or chrome & ie6-ie8 on a windows machine. With onchange it looks to work in all browsers. This issue might be related to the follow chrome bug: https://code.google.com/p/chromium/issues/detail?id=36518.
