Timing Problems in loops. Please Help!

[Thoene]

In my attachment labview program, I am having trouble with my timing.  To give a background: I have random number generators putting out numbers, and every so often I hit my boolean button and it collects the numbers from the generator and finds the mean of the numbers and sends them to a spreadsheet.  But after the first time I press the button, if I press the button before 5 seconds after the first data is collected, it will only collect data until the 5 seconds after the last set of data is collected.      But, I press the button some time after the 5 seconds since the last set of data was collected, it will collect the numbers like usually, but it also collects the data from right when I press the button and then collects it after 5 seconds.  I do not want those numbers right when i press the button.

Is there something wrong with my timing that I get these problems?  Any help would be great!

Thanks in advance

Make the mechanical action of the button "latch when released".

In the innermost loop, wire a "equal zero" between the iteration terminal and the "reset" input of the elapsed time express VI. This will ensure that the timer resets whenever the loop starts.

Place a small wait in the big FALSE case. There is no need to check the button millions of times per second. You cannot click that fast anyway.
