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

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