Took a look at ur script:
Simba Code:
Mouse(x, y, 2, 2, False);
If(ChooseOption('full helm')) Then
So basically what its going to do is to right click, then right after u right click, it will search for the option, BUT due to lag, the option window will not appear immediately after u right click, so it will fail to find.
Even if u loops it multiple times the option is still not going to appear immediately after u right click.
Try adding a wait before ChooseOption (~1-2sec) will solve the problem too, WaitOption is a better solution though.
Also maybe shorten ur string, like just 'elm' or 'ull'.
Add debugs if u still cant figure out the problem
