Problem with new element

[gst77]

Dear Frank,
I'm adding a new element but get errors when compiling.
I have read the guide to add a new element in C ++, the guide to compile and source code of several elements (truss2D.cpp, FourNodeQuad.cpp, ZeroLength.cpp, etc) to write the new element that has 6 materials. Still, I do not succeed to compile the code.
I can send you the file and .cpp .h to tell me that I'm wrong?
I could compile a new material but not the new element.
The file is not complex, but is long to copy here.
Some errors are:

Error 1 error C2440: '=' : cannot convert from 'UniaxialMaterial **' to 'UniaxialMaterial *'
Error 9 error C2601: 'MasonPan::commitState' : local function definitions are illegal

Thank you very much for your help and time!!

these should really be trivial to work through .. i suggest you try before sending as you will actually learn something
