Error in post command: unknown function () post: above message corresponds to expression 1, variable

[Luis Miguel García]

I´m getting an error in my code when using post command but I don´t know why. The code is reproducible with auto dataset:

clear all

tempfile locations
tempname locat

postfile `locat' str32(x1 x2 x3 x4) using `locations', replace

sysuse auto

gen population = 1

gen domestico = 1 if foreign == 0
gen externo = 1 if foreign == 1

gen alto = 1 if gear_ratio <= 2
gen bajo = 1 if gear_ratio > 2

gen cost_h = 1 if price >= 10000
gen cost_l = 1 if price < 10000


local place "domestico externo"
local gear_l "alto bajo"
local cost "cost_h cost_l"


foreach p of local place{
    foreach g of local gear_l{
        foreach c of local cost{
                
        summ population  if `c'== 1 & `g' == 1 & `p' == 1
        local r = r(N)
        
        dis "`p'" "`g'" "`c'"  "`r'"
    
        post `locat' ("`c'")("`g'")("`p'")("`r'")
    
        }
    }        
}

unknown function () post:  above message corresponds to expression 1, variable x1

I´ve tried changing the type of variable in str32() for each variable but nothing works. Thanks

The error message is, perhaps not misleading, but not really informative in this case. You need to put blank spaces between all the () expressions.

Of course! I can't believe it. I was stuck with this a lot. Thanks Mr. Schechter.
