Seperate a value in arduino

Here is your code snippet Auto Formatted in the IDE to show the code blocks

if (gap > gapRangeL[4])
{
  Serial.print("Gap > ");
  Serial.println(gapRange[4]);
  digitalWrite(speedpin1, LOW);
  digitalWrite(speedpin2, LOW);
  if (gap > gapRangeR[4])
  {
    Serial.print("Gap > ");
    Serial.println(gapRange[4]);
    digitalWrite(speedpin3, LOW);
    digitalWrite(speedpin4, LOW);

Notice how much easier it is to see what is going on than your cramped, unformatted version
