Looks like you posted your question twice, I think you can get rid of one.

Also, I'm not sure what you're struggling with exactly from your statement.  The picture works just fine, I just built that piece of code without problems.  Can you show a screenshot of what is wrong?  

If I had to guess without you showing me, I'd guess your array is of the wrong dimensions.  For this to work, it must be a 2D array.

Well, I built too after some struggle since I am a new user. But when I ran, it didn't quite give me the result I expected. Can you also elaborate on how to get 2D array?

Thanks for the image, it looks like you do have a 2D array.  You can tell because it has two index terminals in the upper left hand corner of that pinkish/purplish box with letters in it.  Did you make sure to do the step where it asks you to right click on the multicolumn listbox and select "Visible Items>>Symbols"?  Make sure you checked it and that it has a check mark next to it when you right click on it again.

Oh wow! I totally forgot to check 'Symbol' in multicolumn option. Thank you very much for the help! much appreciated. You might be able to help me out with another thing regarding the application I am building in Labview.

The question is how can I check on or off the boxes in the array? when I run it, it's not letting me check on or off those a,b,c,d rows.

Well, there are two parts to that question.  One, if your application still looks just like that photo then there is no while loop around your code.  That means it will run once and then never again.  So, it will not be in a "running" state when you go to click on those controls.

Assuming you've got that part down, the second problem is that if you have that piece of code in a while loop, you will not be able to edit the controls because every iteration of the while loop will set the controls back to the values you are setting them to programmatically.

Lastly, you'll need to use events to do the editing properly.  Check out the solution to this question:
