MTSRBElementSize and MTSRBSize (+more maybe) inputs not being recieved properly

[Ella Pietraroia]

These variables are always defaulting to their default sizes, there must be something happening when they are received. E.g. when we output the value of the provided MTSRBElementSize in the error it is 0, hence why it is defaulting.

May fix issue #18
