Help with 7-segment/display prompt
Solved!
You need to take a few steps back and think about your code. You are doing things way too complicated. For example, the stop loop and the two timer loops can be combined onto one. The loops run at a fixed pace, no need to measure time, just count iterations!
Why do you need so many stop buttons??? Why are you using such a confusing cluster ordering? Make the displayed number the same as the array index for simplicity!
This is just the toip of the iceberg, there are many more problems. Get rid of the big stacked sequence. You can define execution order with the error cluster.
- Start decrementing the counter at a fixed rate, starting at 60 and stop at 0. (see attached).
- Sust light it up whe the stop condition in (1) is reached. No extra code needed.
- Make a custom popup dialog VI tho enter all you want.

estionoh and 1 more question.. how do I make the LEDs light up at random? thanks.
Your question is ambiguous:
- Do you want to light them up in random order?
- Do you want to light them up at random time intervals?
- Both?
In any case, the "dice" in the numeric palette gives you a random number between 0 and 1. You can use the output to generate either random indices or random time delays.
The numeric constant is outside the loop, so that would not work, of course.
Simply generate a random number inside the loop at each iteration and do the Q&R to get the two random indices.
If this does not make sense, show us your code again.
You need to think this through! Once you generate random indices, you no longer need to increment anything. Why are you dividing by the random number??? You need to divide the random number by three! Some simple probing could have told you that this will not work right!
Here's a quick draft how you could do it.
Also some of your code is absolutely ridiculous. To create a string of consecutive spaces, you don't need to append N space constants. Simply use a string constant with N spaces. Right? Even better, do everything with a simple formatting operation in one step.
Also the way you built an array with two elements boggles the mind. Dont built a 1-element array and then insert the second element using "insert into array". Simply use built array with two inputs (see picture).
