Problem with text parsing application

[Laur]

Hello,

I'm a beginner in labview and i have some problems with my application.

I have at my VI's front panel  an input text box  and two  arrays of strings : one which contains a couple of words that i have to tell if they can be found in the text.

And the other array contains the search results : found or not found

I made my version of the block diagram ( i attached it )  but i noticed that it only works only  the first time that i run the VI , afterwards it displays the same results despite the input text or the words. I find out the my array continued to append new entries each time my for loop runs so i  try to reinitialize the array with constant strings at the beginning but i guess i haven't been doing it properly because i have the same problem.

And i also have another problem : my array of words has it's size = 7 , and if i fill it with less words than it's size , in the results array empty boxes appear as found.

Can anyone gve me a suggestion ?

The first VI attached is my original application where i found the described problems  and the second one contains what i tried in order to fix them

Autoindexing if your friend here (and makes things A LOT simpler).

Also know that the "offset past match" will be -1 if the word was not found.  So you can just do a simple check for the number being greater or equal to 0 to see if it was found.
