Broken wire after for loop

[Comissando]

Hello there,

I am doing some tutorials for the Labview 2009 on the Windows 7.

My problem is that, after a very simple for loop my wire which is connected to the write file vi breaks. The messages of error doesn't help. Thanks in advance.

Tunnel Mode>Last Value does not exist in version prior to 2012.

A very basic function of a for loop is to autoindex an output into an array. This should be covered in the basic LabVIEW tutorials and is explained in the help. Right click on the exit tunnel and select Disable Indexing,

An even better idea would be to replace the tunnels with a shift register. This ensures that the refnum remains valid even if the FOR loop iterates zero times for some reason.
