For loop without N input

[shuishen1983]

Hi Guys,

I have looked at the I/O example and found that the for loop in the example can exist without an input of N. I tried the same thing in the VI created by myself. I think the problem is the type of the tunnel. Can I change the input tunnel into a indexed tunnel? I right-click the tunnel and there is no option to change the tunnel into a auto-indexed one.

The input to the for-loop must be an Array in the case of using auto-indexing and without N being wired.

With out N value the forloop could not execute.

Either give the N count or wire with an array.
