[R] using vif from package "car" - "aliased coefficients in the model"

I have run a simple regression - lm and created a regression object "myreg".
I can see all the coefficients when I print(myreg).
Then I tried to run vif(myreg) from the package "car".
However, it's giving me an error: in vif.lm(regr.f) : there are
aliased coefficients in the model

Very sorry for my question: Is there any way to get the vif's for all

Thank you very much!
