Front derailleur adjustment

[dude]

Hi guys,

I've followed these instructions
http://www.instructables.com/id/How-To-Properly-Adjust-The-Front-Derailleur-On-You
to adjust the front derailleur on a 90's MTB with 400LX components and I think I've done things right, but the chain keeps jumping directly from the outer chainring to the inner one.

Any hint?
Thanks

What kind of shifter's do you have, maybe pics would help

Those are Sti Push Push shifter's. The left has trim built in meaning a small click to clear the derailleur from hitting the cage. These older shifter's gum up with age and hardened grease. Dis connect the cable from the front mech and give tension by pulling with your hand. Click the shifter and make sure it is staying in place for two clicks
