searchbox as3 not working properly

Question

im having a problem where whatever text or even blank space i put i still go in frame 170, as you see i put 171 frame there, and if i type "therefore" it go in 171 , seems like its working fine its just even i put wrong text it go to frame 170 , i cant find the problem tho,also i dont know if i should make an else statement so if the word is not in the list it will go to other frame, thanks mate

 var i:int = 0;
var names:Array = new Array("therefore","disciples","nations","baptizing","father","son","holy spirit");
var frames:Array = new Array("171","170","170","170","170","170","170","170");

button_140.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler_4);

function fl_MouseClickHandler_4(event:MouseEvent):void
{
var searchtext:String = searchtext.text.toLowerCase();
findInArray(searchtext);
gotoAndStop(frames[i]);
}

function findInArray(str:String):int
{
for(i=0; i < names.length; i++)
{

        if(names[i] == str)
        {
    return i;
}
}
return 0;
}

why you always go to frame 170:

let's see your function fl_MouseClickHandler_4:

findInArray(searchtext);//string won't be found so "i" would be 7 (the last index in array)
gotoAndStop(frames[i]);//so it goes to frame 170

a fix for your code:
the function fl_MouseClickHandler_4:

function fl_MouseClickHandler_4(event:MouseEvent):void
{
var searchtext:String = searchtext.text.toLowerCase();
var index:int=findInArray(searchtext);

if(index==-1){
    //do something when frame not found
}
else{
    gotoAndStop(frames[index]);
}

the function findInArray:

function findInArray(str:String):int
{
for(i=0; i < names.length; i++)
{

    if(names[i] == str)
    {
return i;//return the found index
}
}
return -1;//return -1 if nothing found
}

I Hope this helps...

Edit:

You don't need to make a function to find a value in your array. You can use Array class built-in method indexOf() to find the index of an item in an array: see the AS3 manual for more info.

theArray.indexOf(theValue);

returns the index of theValue. if theValue is not in theArray, returns -1.

Test this example below :

//# declare variables outside of function (make once & re-use) 
var searchtext:String = "";
var index:int = 0; 

//# after updating searchtext string with user-text then run function below

function fl_MouseClickHandler_4(event:MouseEvent):void
{
    searchtext = searchtext.text.toLowerCase();
    index = names.indexOf(searchtext); //test with "holy spirit"

    if(index == -1)
    {
        trace("index is : -1 : No match found");
        //do something when frame not found
    }
    else
    {
        trace("index is : " + index + " ::: result is : " + (frames[index]) );
        gotoAndStop( frames[index] );
    }
}
