Start up help request

Hi,

I find the range of models covered in Simbrain to be quite exciting, and I am sure 3.0 will be even richer.  Oddly, however, I find it difficult to do what I (perhaps wrongly) would consider to be the more basic ANN operations.  Perhaps these are not covered, but more likely, I am just not finding the right means.

I want to start with a simple BP network, such as the XOR network here.  I would like to train the network, and observe the decrease in error.

I can open, or create the network, just fine.  I can also open two data-world sets, one for input patterns and one for output patterns.  I change the 'clamped' default of the input units to be 'linear' and set them up so that each receives input from one column of the input data table.  I set the data table to be in 'iterative' mode.  Now when I press Run, the network cycles through the patterns.  

But I am not using the output patterns, nor do I see any commands to train the network or monitor its output error.  I know that there is a BP lesson where the network has a box around it, a BackPropagation label, and if I click on that I get the option to train the network, but I don't see it for a network I create myself, of for the XOR network.

Any help greatly apprecitated!
