Error in age data composition

[Guillermo Caballero Luján]

Hi, im trying to implement age data composition in my model, and I can not figure out what is wrong in the data file. I am following the examples in github for the implementation and i think the lines are correct, but I am getting this error that I do not quite understand

1 L_bin_lo no match to poplenbins in age comp  2002 2.5 1 0 0 1 -1 -1 20

If you remove the age data composition section the model works. 

Thank you in advance.
