[Limdep Nlogit List] Help to estimate equality constrained latent class model

[S Tarfasa]

Dear All,

Would anyone help me estimate equality constraint latent class model as I
was challenged doing it?

I have 9 classes where some respondents ignored one attribute,others all
attributes and the remaining ignored none.I keep getting error when I run
the following syntxa butI couldn't figure it out.
Any help is highly appreciated.

Error   451: Expected  27 specifications in RST/CML list. Found  72.
  Error  1071: Found an error in your ;RST setup. Please check.
  Error  1071: Found an error in your ;RST setup. Please check.
Best,
