Error message "0 (non-NA) cases" linear regression

Hello,

I have an issue with running a linear regression analysis.

I have a dependent variable (ordinal scale, 1-2) and three independent variables (interval scale, 1-8) and coded and defined missing values as "99".

Whenever I am adding a second covariate to the model I am receiving the error message "0 (non-NA) cases".
When trying to run logistic regression it says "Variable 1 has no levels" (screenshot attached).

Did anyone experience the same issue and know how to solve it?

Many thanks in advance for your help!

this usually means that there are no or few combinations of 'Low info-sharing', 'No policy' and 'Short policy' where there aren't missing values.

Hello Jonathan,

Thanks for the explanation.
I've identified the error and computed a new variable.
