Thanks for your response.

Yes Spar_loc should look suspicious. I posted the real error messages but
hid the variable names in the model. Spar_loc is the original form of S.

This did not work. However I did discover something that does:
AAT<- lmer(Y ~ S + A + (1|H %in% S:A), data=AT, REML=TRUE)
Not sure why this worked. I read that it is an alternate way of specifying
This runs without error.
