If you want to wiggle just x and leave y alone you could do it this way:

freq = 7;
amp = 50;
w = wiggle(freq,amp);
[w[0],value[1]]

If you want to wiggle both x and y but with different parameters, you could do it like this:

xFreq = 7;
xAmp = 50;
yFreq = 3;
yAmp = 100;
wX = wiggle(xFreq,xAmp);
wY = wiggle(yFreq,yAmp);
[wX[0],wY[1]]

In expressions, color is represented as an array of [red,green,blue,alpha] where the values have to be between 0 and 1. (Leave the alpha value set to 1 – it doesn’t do anything but it has to be there. So this would be one way to change the color at random every half second:

period = 0.5; // change color every .5 seconds
colors = [[1,0,0,1], // red
          [0,1,0,1], // green
          [0,0,1,1], // blue
          [1,0,1,1], // magenta
          [1,1,0,1], // yellow
          [0,1,1,1]] // cyan

seed = Math.floor(time/period);
seedRandom(seed,true);
idx = Math.floor(random(colors.length));
colors[idx]

That is strange indeed. You might want to drop a line to aebugs@adobe.com.

How about just using the wiggle expression?

First set the value of the parameter to the middle of the range you want and then add an expression like this:

freq = 1.0; //frequency = once per second
amp = 20; // amplitude = -20 to +20
wiggle(freq,amp)

If, for example, you set the value of your parameter to 60 and then added the above expression, your parameter would vary between 40 and 80.

Try this source text expression:

txt = "";
for (j = 1; j <= thisComp.numLayers; j++){
  if (j == index) continue;
  L = thisComp.layer(j);
  if (! (L.hasVideo && L.active)) continue;
  if (time >= L.inPoint && time < L.outPoint){
    try{
      txt = L.source.name;
    }catch(err1){
      txt = L.name
    }
    break;
  }
}
txt
