Cancel Event; Command

[jonu14]

Hi,
I'm currently working on my new script, however, I don't get on with this part;

As you can see, I'm German, so the text is also German, but hopefully that will not stop you from recognizing the mistake c:
first if-condition:
Shows the player, how many warns he already has.
second if-condition:
Does the same, except for a little grammatical change.
(1 warnings to one warning)
The problem is, I'm not able to do that within a command.
Output message:

The first line corresponds to the 1st If-Condition, the second line to the 2nd If-Condition.
I don't want the first line to show up, but "cancel event" is useless.
Can you help me? Would be very nice from you c:

command /warns:
    permission: elite.player.see.warns
    trigger:
        if {verwarnungen.%player%} is 1:
            message "&7Du hast &8eine &7Verwarnung"
        else:
            message "&7Du hast aktuell &8%{verwarnungen.%player%}% &7Verwarnungen"

I don't know if this is exactly what you want but I am assuming it is this. Also, if you have the permission listed in the top, you will not need it in the code itself.
