1. Get rid of that FOR loop.  It is not doing anything for you.

2. You should create a 1D array of your two numbers and then append that to your table data.

3. I highly recommend keeping your table data in a shift register.  It will make your process A LOT more efficient.

OK, now you need to learn about "event structures". There are some really good tutorials online.

ok going to read about event structures, mihgt be a good tip

if im trying something and it does not work ill post my block daigram here

thanks

So i tried the event structure, and this is what i made, it works might be not as others do but im new to it.

While running the program an do empty table and import new values the old values after empty table

appaers again ( strange), what i also tried is data operations make current value default but does not work,

can someone help me ?

No, none of that is correct. The event structure should contain the code you want to execute when then button is clicked. You have all of it outside the event.

[crossrulz]

Your code should look something like this.  Remember that the event structure will keep your loop from iterating until it handles an event.  So you want everything you want to happen when you press that button to be in that event case.  You cant' see it directly in this snippet, but I am also handling the Stop button's value change event and using that to tell the loop to stop.  You alos need to make sure your array is passed through all of your cases or you can lose your table data.
