Using the Neural Network toolbox, why do I get more solutions than I should be getting?

I created a neural network using the fitting tool. Inputs were 98x2 whereas Outputs were 98x1. After the network called "net" was created, I tried to simulate it using the command (y1=sim(net,[numbers looking outputs for])). Normally, I should be getting 1 answer for the two input values that I chose. However, for some reason I am getting as many answers as inputs. Any idea what might be causing that?

Thank you

Transpose your data matrices

 [ I N ] = size(Input)

 [ O N ] = size(Output)
