I have a problem: why is calling the variable form static_chr.

all code:
turf
    var
        from
    icon='box.dmi'
    chr
        icon_state="blue"
        static_chr
            var
                chr
                clr
                bgc
            New()
                .=..()
                text = "<font bgcolor='[bgc]' color='[clr]'>[chr]"
    text
        icon_state="green"
        static_text
            var
                txt
                clr
                bgc
            Click()
                .=..()
                for(var/r = 1,r<=length(txt)+1,r++)
                    var/turf/chr/static_chr/ch = new(locate(x+(r-1),y,z))
                    ch.from = src
                    ch.clr = clr
                    ch.bgc = bgc
                    ch.chr = copytext(txt,r,r++)
                del src


runtime

i repaired the problem:

replaced
var/turf/chr/static_chr/ch = new(locate(x+(r-1),y,z))

whit
var/turf/chr/static_chr/ch = new(locate(x+r,y,z))

because t5he turf, when is created, recplaces the turf in location.
