• Place an array indicator to show the array of random numbers.
• Show just one element of the array.
• Set the index to show the 5th element.
• Hide the array index.

Finished…

On your VI:

• Why do you set the condition of the conditional tunnel to TRUE? (When the condition is always TRUE, then there's no need for a conditional tunnel…)
• Why don't you use the comparison result of "i" with 4 as condition?
• You still get an array output after the conditional tunnel so you still need IndexArray to show a scalar result. It would be much easier to use the same IndexArray function to pick the 5th element from the array of the default indexing tunnel…

If you want a scalar, the conditional tunnel cannot be set to indexing.

The condition belongs at the conditional terminal (bottom!) and the number at the "last value" tunnel. ( you get the last value where the condition was true, i.e. i=4)
