[Flash] loading dynamic text

[BRaiNRaiN]

Hai! I hope there are some Flash experts in UTA

i'm doing stuff for uni (im a complete flash / code noob) but im walking into some troubles.
I'm working on a interactive map and every time I click on a place it should load some text, which stands in an dynamic textbox, like this:

on (release){
TextboxSluisI._visible = true;
TextboxSluisII._visible = false;
TextboxSluisIII._visible = false;
TextboxSluisIV._visible = false;
TextboxSluisV._visible = false;
TextboxDeelenlaan.visible = false;
TextboxWaalstraat.visible = false;
TextboxLijnsheike.visible = false;
TextboxHeikantsebaan.visible = false;
TextboxEnschotsestraat.visible = false;
TextboxBosscheweg.visible = false;
TextboxOisterwijksebaan.visible = false;
TextboxTrappistenbrug.visible = false;
TextboxBiesthoutakker.visible = false;
TextboxHolenakker.visible = false;
TextboxKattenberg.visible = false;
TextboxGroenewoud.visible = false;
TextboxHeuvel.visible = false;
TextboxHoutens.visible = false;
TextboxSon.visible = false;
TextboxHooydonk.visible = false;
TextboxStadvanGerwen.visible = false;
TextboxOranjelaan.visible = false;
}

every time I make one textbox active.. the first five textboxes worked.. but the 6th didnt anymore..
Is Flash restricted to 5 dynamic textboxes or something? And How can I solve it? Dunno any programming so loading xml files or so.. dont know what to do

HEEEELP! i'm clueless!
