Error parsing MIB file

Error parsing MIB file

Hello,
 
When I try to upload a new MIB table, I got this error : Error parsing MIB:PHION-MIB.txt
Exception while loading MIB:Could not parse the file D:/Program Files/ManageEngine/OpManager/./mibs/PHION-MIB.txt. The error occured at the line no: 77 ,column: 24. The identifier should not start or end with number or special character.
 
Could you please correct my MIB table?
 
Thank you for your help!
