You asked this before and you are still not providing sufficient
Harold already pointed out that excluding an important variance
component in SPSS could easily explain a difference in p values.
However, the discrepancy between CI and p value suggests that you could
be misreading the output from lmer(), and/or misspecifying the model.
Now, you are simply not telling us
- what you did
- what the data are like (esp. which variables vary within and between
- what the output was
- which version of lmer() was used
Also you are confusing us with "variable 1", "variable 2", "variable A",
and "Var B"
