Problems loading ::quartus::sta

Hi,

I was trying to setup a tcl script and in it I loaded the packages I needed:

package require ::quartus::project

package require ::quartus::flow

package require ::quartus::sta

When I ran the tcl script, it was able to load the first two packages but gave me an error for the ::quartus::sta package - saying it cannot find this package.

Any idea where I went wrong?

Regards
