Question Get custom parameter via code

I have an fbx created with maya, with animation clips containing custom parameters.
I have imported correctly the fbx ticking the flag "Animated Custom Properties" but I don't know how to access the parameter via code.

Someone posted about adding a float parameter to the animator with the same name of the custom parameter but that desn't work for me. The parameter doesn't change in the Animator even if I name it with the same name.

Any suggestions?.

 

Reimporting the model has worked, nevermind.
