I created an Array with captions and now I want to make it so when I press one of the buttons it will make the caption appear. For this I have used a For loop.

_thumbNailCaption_\* does trace the variables I’ve assigned, but I can’t get _thumbNailCaption_.textDisp\* to trace anything like it. No matter how many variations I’ve made, it always comes out undefined! Does anyone know what I’m doing wrong?

> stop();

// CREATES AN ARRAY TO HOLD THUMBNAIL COMMENTS  
var thumbNailCaption = new Array();  
thumbNailCaption[0] = “abc”;  
thumbNailCaption[1] = “def”;  
thumbNailCaption[2] = “ghi”;

// BUTTON PROPERTIES  
for (i = 0; i \< 12; i++) {  
\*\* this[“thumbNailCaption”+i].textDisp = thumbNailCaption\*;\*\*  
mcBody.mainBody[“thumbNail”+ i].onRelease = function() { \_root.mcBody.mainBody.textCaption.textDisp = this.textDisp;}  
}
