User Friendly Input Variable Names

Hi,

I've seen this feature in MQL4 post build 600 -

" It is possible to set another way to display names of input parameters in the Inputs tab. To do this, a string comment is used, which should be located after the description of an input parameter in the same line. Thus, names more understandable for a user can be matched to input parameters."

Example:

 However I can't seem to get it to work.. Here is my code:

input int level=25; // Alert Level
input int adxp=14; // ADX Period
input enum_TimeFrame TimeFrame=15;// Time Frame
input bool popup=true; // Use Popup Message
input bool sms; // Use Cellphone Alert
input bool email; // Use Email Alert
bool AlertOn=false;

Any idea what I am doing wrong? I am using version 4 build 840.

Thanks

Richard
