Well, a few bugs and/or omissions:
1. SQRT should be Sqrt and be using square brackets and no parenthesis
2. Dataspectrum is undefined
3. AppendTo[DataGood, {EisonewOm, Lx, z, idGRB, Om, O}], contains a
undefined variable O which is also a reserved Mathematica symbol
4. AppendTo[LxOmegaM, {Om, Ol, CLxEiso}], contains the undefined
variable Ol
5. second to last line: Flatten[LxOmegalambda, 2] doesn't do anything
because you don't assign the results to a variable
