[ADMB Users] no gradient 2.0

[Mollie Brooks]

Hi all,
Somehow my parameters have no gradients. I know Alex Campbell had a similar problem in Feb, but looking at that list history didn't give any insight into my problem so I'm here to ask for help.

My function value is reasonable, but there are no Gradients.

If anyone has any ideas, I would be really grateful.
thanks,
