[Solved] syntax error, unexpected: "takes"

[Death Adder]

For some reason I keep getting an error with this function below, specifically Syntax Error, unexpected: "takes" on this line function Demonic_Flames_Targets_Filter takes nothing returns boolean

function Demonic_Flames_Targets_Filter takes nothing returns boolean
    local unit u = GetFilterUnit()
    if IsUnitEnemy(u, GetTriggerPlayer()) == true and IsUnitType(u, UNIT_TYPE_GROUND) == true and IsUnitType(u UNIT_TYPE_STRUCTURE == false then
        return true
    endif
    return false
endfunction

Here's the whole trigger:

globals
    real dem_fla_dmgInc = 50                                                //per level increase of base damage
    real dem_fla_dmgBase = (100 - dem_fla_dmgInc)                           //base damage
    real dem_fla_dmgMulti_inc = 0.2                                         //how much attributes increase the damage by (per level)
    real dem_fla_dmgMulti_base = (1 - dem_fla_dmgMulti_inc)                 //how much attributes increase the damage by (base)
    real dem_fla_range_radius_inc = 15                                      //how big the AoE increase per level is

Look at the highlighted code in your very own post. You wrote endfuction instead of endfunction right above the reported function.

Don't forget to pair up the parentheses as well.

function Demonic_Flames_Targets_Filter takes nothing returns boolean
    local unit u = GetFilterUnit()
    if IsUnitEnemy(u, GetTriggerPlayer()) and IsUnitType(u, UNIT_TYPE_GROUND) and (not IsUnitType(u UNIT_TYPE_STRUCTURE)) then
        return true
    endif
    return false
endfunction

Yeah I found a lot more problems afterwards, and also apparently you can't have a callback function take anything, so I had to use globals as well. But I've fixed the trigger now at least.

The issue in the OP was just that I kept trying to figure out what the problem was with the line that gave the error message, when I should've looked at the previous function instead.
