Ambient ceiling lighting project for Dolby 5.1 sound for PC

Ok I'm at the point where i need help with the code... If anyone can assist i will greatly appreciate that. This is where I am currently with the code..

Number 720
LedCenterShift = 9 //Width Of Trailing Led's, shifted from center Starting Point
TrailSize = 9 //Number of Leds to Shift
TrailColor = 192,192,192 //lightgray = 211,211,211, silver = 192,192,192, darkgray = 169,169,169, gray = 128,128,128
FLStop = 180	//Speaker Front Left To LED Location
FRStop = 0	//Speaker Front Right To LED Location
RLStop = 360	//Speaker Rear Left To LED Location
RRStop = 540	//Speaker Rear Right To LED Location
FLFRStart = 90	//Center Of Front Left and Front Right Speaker
FLRLStart = 270	//Center Of Front Left and Rear Left Speaker
RLRRStart = 450	//Center of Rear Left and Rear Right Speaker 
RRFRSrart = 630	//Center of Rear Right and Front Right Speaker
int FRONTW2FL[] = {90,91,92,93,94,95,96,97,98} //Front Side Wall to Front Front Left Array
int FRONTW2FR[] = {90,89,88,87,86,85,84,83,82} //Front Side Wall to Front Front Right Array
int LEFTW2FL[] = {270,269,268,267,266,265,264,263,262} //Left Wall Center to Front Left Array
int LEFTW2RL[] = {270,271,272,273,274,275,276,277,278} //Left Wall Center to Rear Left Array
int REARW2RL[] = {450,449,448,447,446,445,444,443,442} //Rear Wall Center to Rear Left Array
int REARW2RR[] = {450,451,452,453,454,455,456,457,458} //Rear Wall Center to Rear Right Array
int RIGHTW2RR[] = {630,629,628,627,626,625,624,623,622} //Right Wall Center to Rear Right Array
int RIGHTW2FL[] = {630,631,632,633,634,635,636,637,638} //Right Wall Center to Front Right Array

void loop() 
{
if (channelFL =< 10) 
for (int i = FLFRStart+LedCenterShift; i <= FLStop; i++)
{ FRONTW2FL[i] = CRGB::TrailColor;
FastLED.show();
delay(20);
}
if (channelFL => 9)
(int i = FLStop; i >= FLFRStart+LedCenterShift; i++)
{ FRONTW2FL[i] = CRGB::TrailColor;
FastLED.show();
delay(20);
}
if (channelFR =< 10)
(int i = FLFRStart-LedCenterShift; i <= FRStop; i++)
{ FRONTW2FR[i] = CRGB::TrailColor;
FastLED.show();
delay(20);
}
if (channelFR => 9)
(int i = FRStop; i >= FLFRStart-LedCenterShift; i++)
{ FRONTW2FRi] = CRGB::TrailColor;
FastLED.show();
delay(20);
}

So at this point I'm just going to work with the front wall code for the moment until someone can spot check me to let me know if I'm going about it right and or if the code is good before i move forward. So on the front wall strip of LED's i have 180 LEDS with a center point of 90. what i would hope for in the code above is to have 9 LED's to the left of the 90th LED and 9 to the Right. I've created an array to hold the LED's and if the sound channel channelFL is greater than 10 the LED's to the left of the 90th should trail from its starting point to the end point that i defined at FLStop which is LED 180 then trail back to its starting point if the channelFL value drops below 10. I also did this same code for the Front Right channel which should sit 9 LED's to the right of the 90th LED and trail to the right under the same conditions for the channelFR values. I considered making the center shift value 10 to make a slight space between.

Thank you,
