Distance - Color RGBLED + Distance sensor HC-SR04 (having strange results)

working with a greater distance, firing sensors individually, more stable output:

var distanceR = 0;
var distanceG = 0;
var distanceB = 0;
var running;
var c=0;
var sensorR = require("HC-SR04").connect(A0,A1,functio­n(dist) {
  if (dist < 300 && dist > 0) distanceR = dist;
});
var sensorG = require("HC-SR04").connect(A2,A3,functio­n(dist) {
  if (dist < 300 && dist > 0) distanceG = dist;
});
var sensorB = require("HC-SR04").connect(A4,A5,functio­n(dist) {
  if (dist < 300 && dist > 0) distanceB = dist;
});
SPI2.setup({baud:3200000, mosi:B15});
function runIt(){
  if (c===0) sensorR.trigger();
  if (c===1) sensorG.trigger();
  if (c===2) {
    sensorB.trigger();
    sendToLeds();
    c=0;
  } else c++;
}

function sendToLeds(){
    
  //console.log("before("+Math.floor(dista­nceR)+","+Math.floor(distanceG)+","+Math­.floor(distanceB)+")");
  
  if(distanceR > 100 || distanceR === 0){distanceR = 0;} else {distanceR = 255-(distanceR/4)*10;}
  if(distanceG > 100 || distanceG === 0){distanceG = 0;} else {distanceG = 255-(distanceG/4)*10;}
  if(distanceB > 100 || distanceB === 0){distanceB = 0;} else {distanceB = 255-(distanceB/4)*10;}
