Photoshop: Why is size jitter under Shape Dynamics is greyed out?

Size Jittler under Shape Dynamics under Brush settings is somehow locked or greyed out so Im not able to use it even though my Wacom Intuos Pro is plugd in. Plz help me so I can use pressure sensitivity,

Hi Victor,
I am guessing that you are using a Bristle tip brush. For those brush types size jitter is not an available option. The size of the mark is determined by the deformation of the tip with pressure. This is the case for all 3D based brushes. (Bristle, Erodible and Airbrush)

Hope this helps,

Hi Mike, Someone else posted that question but it was the same I had. I never considered the type bristle. I was going crazy trying to figure it out! Thanks!
