My popups look nothing like yours, I was just commenting on what was wrong with yours.

is an invalid line, so it won't be displayed in your right-click menu. You need to add a command to the right of the colon:

It looks like someone's been editing your popups.ini with notepad instead of using the alt-p window, but since notepad was used to screw it up, you need to use notepad while mirc isn't running to fix it. Each section of the file has lines beginning like n0= n1= etc. You earlier fixed the problem where n0=/n1=/ n2 weren't in the right order. However, you also have n6= and n7= repeating several times. You need to edit the file to renumber that section so you don't repeat the line index numbers.
