[Gate-users] Error in forbid command

[lupa euy]

Dear everyone, 

I am running my PET simulation using GATE6.0 p01, it runs alright but once I include the Forbid command for the cold region, 
it gives such error below.... 
 
If the Forbid command was not there, or it does not declared properly (and hence it is ignored), the simulation went well..but no cold region is defined. Below is the error comments and how I defined the source in the source and cold region in the mac file.

Anybody have any idea what is going on ? please help.. 

regards
