Hi there,

I need a little help to resolve this in AS 2.0 Flash 8:

I want to load status from a txt file, to retrieve which one of 3 layers should be visible in order to display the status of each of 40 lands to be sell on my a map.  
The content of my text file is organized like this:

lot\_01\_a=false&lot\_01\_v=true&lot\_01\_c=false&lot\_02 \_a=true&lot\_02\_v=false&lot\_02\_c=false…

Here is my AS:

myVariables = new LoadVars();  
myVariables.load(“terrains.txt”);  
myVariables.onLoad = function(success){  
if(success){  
for (var i = 1; i\<41; i++) {  
if(i \< 10){  
trace(“test: “+this[“lot\_0”+i+”\_a”]); // OK display “test: false” (as example)  
trace(“test: “+this[“lot\_0”+i+”\_v”]); // OK display “test: true” (as example)  
trace(“test: “+this[“lot\_0”+i+”\_c”]); // OK display “test: false” (as example)  
// HERE I NEED TO SET MY LAYER VISIBILITY AND IT NEVER WORKS !!!  
eval(“lot\_0”+i+"\_a").\_visible = eval(this[“lot\_0”+i+"\_a"]); // DON’T WORK  
eval(“lot\_0”+i+"\_v").\_visible = eval(this[“lot\_0”+i+"\_v"]); // DON’T WORK  
eval(“lot\_0”+i+"\_c").\_visible = eval(this[“lot\_0”+i+“_c"]); // DON’T WORK  
}  
else{  
// HERE I NEED TO SET MY LAYER VISIBILITY AND IT NEVER WORKS !!!  
//set ("lot_”+i+"\_a._visible", eval(this["lot_"+i+“_a"])); // DON’T WORK  
//set ("lot_”+i+"\_v._visible", eval(this["lot_"+i+“_v"])); // DON’T WORK  
//set ("lot_”+i+"\_c._visible", eval(this["lot_"+i+“_c"])); // DON’T WORK  
//setProperty(eval("lot_”+i+"\_a"), _visible, this["lot_"+i+“_a"]); // DON’T WORK  
//setProperty(eval("lot_”+i+"\_v"), _visible, this["lot_"+i+“_v"]); // DON’T WORK  
//setProperty(eval("lot_”+i+"\_c"), _visible, this["lot_"+i+“_c"]); // DON’T WORK  
//eval("lot_”+i+"\_a")._visible = this["lot_"+i+“_a"]; // DON’T WORK  
//eval("lot_”+i+"\_v")._visible = this["lot_"+i+“_v"]; // DON’T WORK  
//eval("lot_”+i+"\_c")._visible = this["lot_"+i+“_c"]; // DON’T WORK  
this["lot_”+i+"\_a"]._visible = this["lot_"+i+“_a"]; // DON’T WORK  
this["lot_”+i+"\_v"]._visible = this["lot_"+i+“_v"]; // DON’T WORK  
this["lot_”+i+"\_c"]._visible = this["lot_"+i+"\_c"]; // DON’T WORK  
}  
}  
}  
else {  
trace(“there was a problem loading the variables”);  
}  
}

As you could see I tried a lot of things without success.  
However, the following with hardcoded values works well wich tells me that my instance are correctly named:  
eval(“lot\_0”+i+"\_a").\_visible = false; // WORKS !!!  
eval(“lot\_0”+i+"\_a").\_visible = true; // WORKS !!!  
eval(“lot\_0”+i+"\_a").\_visible = false; // WORKS !!!

Thank’s a lot for helping…:red:
