Condition checking in Action Messages

[anuradha]

Hi,

I need to check the condition in Action messages.
Could you please help me how to put condition in messages.

EX:

if {{HOSTNAME}:folderstatus.last(0)}="folders are ok"
message: folders are ok
else
message {{HOSTNAME}:folderstatus.last(0)}

Regards,
Anuradha
