Invisble Abilty button?

How can I make an ability button invisble like "Invurablity" (I know spelling). I really need some help here. If triggers are needed then I do it but I can't do any JASS so you gotta help me out there if its needed.

So what you want is for an ability that normally has a button in the command card to not show any button?

Unless the ability is also an item ability with no icon, I think you're stuck. There's a trick to giving icon-less abilities icons (by using dummy abilities) but not vice versa.

Ok but thanks for your help

try to place the button at 0,0 instead of 2,2 for example, not sure if it might work lol.. or just try to give no tooltip, and to take a screenie of a skill slot, and set the icon's art to it. you gotta set all players to a specifiec race...or it will look weird, i dont know if the first suggestion works, but i hope so
don't forget to set the highest resolution and texture if you take a screenshot of a dummy icon, if you take a screenshot with a 8x6 rez and low texture it wont look good for someone with good settings
