How to define the hydrogen liquid?

Dear fluka experts,
     I want to define a material of hydrogen liquid but I obtain the
following error for using the different MATERIAL card respectively,

MATERIAL 1. 1.007947 0.06 28. 0.0
0.HLIQUID
LOW-MAT HLIQUID 1. -2. 87. 0.0
0.HYDROGEN

  *** (n,p) proton production activated for Xsec mat. # 1 ***

  HYDROG-1

What is wrong with my material definition ? And how to define the
hydrogen liquid correctly? The version for fluka is 2008.3.5(the latest
version from the fluka site).
