how to view the values of variables declared inside for ODE Evolution Page in EJS?

For example,
[code]double deltax = x-x, deltay = y-y; //
double deltaVx = vx-vx, deltaVy = vy-vy;
double distance = Math.sqrt(deltax*deltax+deltay*deltay)-diameter/2*2;  //
if (deltax*deltaVx+deltay*deltaVy<0) {
return distance;
}
Action:
[code]double vcmx = (vx+vx)/2;  // vcm is center of mass velocity in laboratory
double vcmy = (vy+vy)/2;
double deltax = x-x, deltay = y-y;
double r=Math.sqrt(deltax*deltax+deltay*deltay);  // separation
deltax = deltax/r;  // normalized separation x component
deltay = deltay/r;  // normalized separation y component
// transform into CM system
vx=vx-vcmx;
vy=vy-vcmy;
vx=vx-vcmx;
vy=vy-vcmy;
// compute collisions
double dot=deltax*vx+deltay*vy; // particle 0 projection along line of centers
vx=vx-2*dot*deltax;
vy=vy-2*dot*deltay;
dot=deltax*vx+deltay*vy;        // particle 1 projection along line of centers
vx=vx-2*dot*deltax;
vy=vy-2*dot*deltay;
// transform into laboratory
vx=vx+vcmx;
vy=vy+vcmy;
vx=vx+vcmx;
vy=vy+vcmy;

[/code]

I normally recreate the variables in event in the main variable tab/page and copy and paste the relationship/equation in "fixed relations tab" to track the values as the simulation run.

Example of Fields: that i want to see what they are calculating
deltax = 0.00
deltay = 0.00
deltaVx = 0.00
deltaVy = 0.00
distance = 0.00

is there an easier way to do track variables declared inside the event and for the matter custom functions ?  ;D Thanks!
