Find and warp to nearest ammunation

[AGENT_STEELMEAT]

Looks like I'm on a roll today.

I've been looking at different ways to find the nearest ammunation and warp to it, and this is what I've come up with:

  
ammunations = { 
  { 2150.1499023438, 936.83428955078, 10.306272506714 }, 
  { 782.69812011719, 1872.9688720703, 4.4971857070923 }, 
  {-1508.8366699219, 2603.4729003906, 55.322311401367} 
} 
  
function findNearestAmmunation(thePlayer) 
  local nearest = nil 
  local min = 999999 
  for key,val in pairs(ammunations) do 
    local xx,yy,zz=getElementPosition(thePlayer) 
    local x1=val[1] 
    local y1=val[2] 
    local z1=val[3] 
    local dist = getDistanceBetweenPoints2D(xx,yy,x1,y1) 
    if distthen 
      nearest = val 
      min = dist 
    end 
  end 
  return nearest[1],nearest[2],nearest[3] 
end 
  
addCommandHandler("warp", function() 
  local xx,yy,zz = findNearestAmmunation(source) 
  spawnPlayer(source,xx,yy,zz) 
end) 
  

I get a "attempt to compare boolean with number" error at line 16. I'm totally lost here, I've been working on this for hours.

Any help is once again apreciated.
