This question already has an answer here:

I am writing a program for which I did a My Block. I later realize that I need to add a new input parameter and I can't find a way of doing this without creating a new My Block. This seems it should be trivial but its driving me crazy not being able to find out how. Any help would be very much appreciated. Thanks

Unfortunately, there is no way to add a parameter to an existing MyBlock in both the NXT and EV3 series. You will have to create a new one with more input parameters.
