Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Okay I'm trying to put Hidden Power Grass on one of my Pokemon but it isn't working. I have the attack Hidden Power on the Pokemon and on the stats page I have Grass selected for the Hidden Power slot. What am I doing wrong?
Can you define "not working"? Is it a legendary Pokemon? If so, there are certain IV spreads that are illegal with certain Hidden Powers. If you can give us a bit more information we might be able to help!
I was trying to get Jolteon Hidden Power Grass. I gave it the attack Hidden Power and then set the Hidden Power to grass in the stats window. However when I go into battle the Pokemon will have Hidden Power Normal, not Hidden Power Grass.
When you actually use the move in battle, it will work as a grass-type move. Hidden Power itself is always normal; it merely takes on the effect of the type you select once you use it.
