print where, find problem

Hi,
i can’t find error in this…I have 20 drop rules in my /ip firewall filter table but if i execute this command i get nothing…

:put [/ip firewall filter find action=drop]

or

:put [:len [/ip firewall filter find action=drop]]

returns 0

Where is the problem? I tried version 4.5, 3.30, 3.10…

it’s a feature =)

:put [/ip firewall filter find action="drop"]

Thanks!

I tried

:put [/ip firewall filter find action='drop']

but I shoud have tried also ".
