I need help with scar/smart

I changed all the Smart.scar, and srl.scar files and i still have problems.
I am getting a problem when trying to run a script, i started getting this error when setting up SMART, so i expect i am not the only one.
The problem is everytime i try to run the script, this error shows up,
unknown identifier 'SmartIsKeyDown' in script C:\Program Files\Files\Scar 3.15\includes\SRL\SRL\Misc\smart.scar

What is wrong?

 

same heer i need help bad

 

smart isnt really very reliable. i would recommend using the good old version of scar.
