Does anyone know why this formula reports error: /gr {1d20 + 8}>=@{target|AC} as well as this one: /gr {1d20 + 8}>= @{target|AC} \space added between = @ I want it to declare success or failure on roll equal or higher than target's AC. I have also tried with these combinations: => I have also tried like this: /gr {1d20 + 8} >=@{target|AC} in which case it just takes >=@{target|AC} as text. Thanks for help. Emil
