connecting physical channels to virtual channels

Hi,

I am working on a project that turns on/off four valves. I am connecting four physical channels to a virtual channel and I am getting an error message that follows:

"Write cannot be performed because the number of channels in the data does not match the number of channels in the task.

When writing, supply data for all channels in the task.

Alternatively modify the task to contain the same number of channels as the data written.

Number of channels in Task: 1

Number of channels in Data: 4"

I am trying to connect each physical channel to a boolean in an array, can someone look at my VI and see what I am doing wrong?

Many thanks in advance.
