Hi Petr,

Thank you so much for your help.

You're right, the issue was that I needed to center my predictors by adding
the code 'na.rm=T':

verbal.ability_C <- verbal.ability - mean(verbal.ability, na.rm=T)

That removed the NA values from being included in my centering and allowed
me to run the regressions.

Again, I really appreciate your help.
