Hello everyone

I am new to OpenFoam and I am trying to run a simulation of a pipe. When I try to run the command "gmshToFoam", I get a lot of errors saying I don't have 3D elements in my mesh file. I don't know where to go from here. I have put my geo file code below. Can anyone please help me out?

Code:
