Indicators Not Working-Help

 
I have downloaded several indicator's to my MT4 platform and they show up on the custom indicators list. but when I attach them to the chart nothing happens. It shows the indicator being there but that is it.  Can someone please assist me in getting these indicators to work Thanks.
 
Make sure that all indicators are compiled and have appropriate files with ex4 extension
