No variance for an IV in a group PreviousNext

I'm using multigroup analysis with 5 groups. One of the IVs has variance in some groups, but no variance in others.

When I try to run the analysis, Mplus reports that "One or more variables have a variance of zero", and stops running.

Is there anyway I can use this IV at all for my analysis?

I would either not use the variable or not use the group in which it has no variance.
