i absolutely hate it when i get this:
bios:337: [string "airdrop"]:81: '=' expected

my first thoughts was i was passing bad arguments to the script, because text needs to be serialized and unserialized back out, but after testing with raw values, i still get the same error. i even noted getting a different error when giving it wrong values

the thing as a whole is supposed do emergency airdrops on a peripheral glasses user who specifies coords for the drop.
some values are only half in use.

line 81 is the first v=v+1 in startMission(), obviously nothing around there is broken/needing = signs

*plop*
x, y, mode = {...}
rednet.open("right")
--0 is south (3 is sunrise)
print("starting")
face = 0
startPos = {-120,224}
--startHeight is the height of the block its on
startHeight = 63
travelHeight = 128
function calculateTurn(direction)
--the wierd calculation magic and i ran out of ideas for value names
pi = direction - face
--determine two lefts or a 180
if math.abs(pi) == 2 then
  turtle.turnLeft()
  turtle.turnLeft()
  face = face+2
  --determine right turn
  elseif pi == -3 or pi==1 then
  turtle.turnRight()
  face = face+1
  --determine left turn
  elseif pi == -1 or pi==1 then
  turtle.turnLeft()
  face = face+3
end
if face > 3 then
face = face - 4
end
function HudNotice()
message = {}
message[1] = "note"
message[2] = ("beginning airdrop on: " .. x .. " " .. z)
rednet.send(0,textutils.serialize(message))
function greenlight()
fuelInBlocks = turtle.getFuelLevel() + (96*turtle.getItemCount(1))
if (fuelInBlocks - totalDistance)<0 then
  error = {}
  error[1] = "urgent"
  error[2] = "Airdrop Delayed! Out of Fuel"
  rednet.send(0,textutils.serialize(error))
  os.reboot()
end
--check items?
--and we are good to go
end
function determinePath()
--find some directions
if startPos[1]>x then
  firstturn = 3
  elseif startPos[1]>x then
  firstturn = 1
  elseif startPos[1]==x then
  firstturn = face
end
if startPos[2]>z then
  secondturn = 0
  elseif startPos[2]<z then
  secondturn = 2
  elseif startPos[2]==z then
  secondturn = face
end
--distance is in absolute value
distanceX = math.abs(math.abs(x)-math.abs(startPos[1]))
