[amibroker] Parameters window doesn't show parameters

["cyclicaltrader" <trading@xxxxxxxxxxxxxxxxxx>]

Hi,

I wrote a couple of custom indicators but when I insert them on a
chart sheet, the parameters window is blank.  The indicator draws
properly below the chart.  When I right click on it, and select
"Parameters", I see the parameter options properly.

Any ideas why this is happening?

Thanks
