calculated using the updated x and not the correct (original) one.

Dear group, I cannot figure out why the calculations inside [expr (x*cos(theta))-(y*sin(theta)); (x*sin(theta))+(y*cos(theta))] gives me wrong results.The above mentioned formula for rotation is correct. I initialize the values through [value] object before preforming computation. The initial values are: x=1, y=0, theta=1/2pi. I expect the new x and new y to be (0,1) respectively after the rotation. But, for some reason, I get (-1,1). I checked the help files for [value] and [expr] and it looks like I am doing everything right.Anyone have an idea where's the mistake? Thank you!
