ActionScript 2.0 :: Save Date With The Ability To Edit Later

I have an app that allows you to save data into a database and gives you the ability to edit that data at a later date. Let's say the user saves
"Up to 90% off retail price"

Everything works fine, the % gets saved in the table etc. The problem is when they return to Flash it now reads
"Up to 90 off retail price"

All I'm doing is taking the value of the variable and sticking inside a text box, I can't see why Flash is having trouble reading that value into a text box. I am making this data into an html ready textbox.

Code:
The % can be in any of the array element values
listValues[10], etc....
Property Values Array
editedPropertyHighlights = new Array(listValues[10], listValues[11], listValues[12], listValues[13]);
// POPULATE TEXTBOX
for (i=0; i<editedPropertyHighlights.length; i++) {
_root.base_front.display_txt_6.html = true;
_root.base_front.display_txt_6.htmlText += "<li>"+editedPropertyHighlights[i]+"</li>";
}
