Replacing default text

[bunglebrown]

hope everyone is well. . .

a relatively simple one here possibly: I am looking to replace the default text that users enter in an input box using flash. This is what I have found whilst sniffing around but cannot make any of it work of course - sorry I have a long way to catch up.

var clearInputValue = Array();  
function clearInput(from_addr){  
    if(!clearInputValue[from_addr]){  
       clearInputValue[from_addr] = from_addr.value;  
       from_addr.value = "";  
       from_addr.style.color = "black";  
    }  
 }  
 function replaceInput(from_addr){  
    if(from_addr.value == ""){  
       from_addr.value = clearInputValue[from_addr];  
       from_addr.style.color = "#999999";  
       clearInputValue[from_addr]= false;  
    }  
}
