extended kalman filter simulink block won't accept additional inputs

I'm using the EKF block in simulink, the block recives the current state vector (denoted on the block as y1) and outputs the state estomation (x_hat). inside the block itself you need to define a state function using a matlab .m file, if you define the state function to have more than one input then another input port shows up on the block, when I try to run the model with a the new input port connected to some constant value block then an error shows up saying the state function has an unsupplied input. I can't understand what I'm doing wrong, does anyone have any idea?

thanks alot in advance,

The problem was in another block in the model, I was calling my state transition func without giving it the right inputs inside a diffrent function.
