edit fields with eval expressions

I am receiving an error of "The expression is malformed. Expected IN." any time we search utilizing the web data model. When i remove this eval expression 'if(act="File quarantined","blocked",action)' the search works fine so I am assuming that this is the problem child. does anyone see anything inherently wrong with this expression?

Where are you seeing this? Inside the web datamodel?

In which case, the action field should look like this (see attached)

If you really want to include that additional logic into the datamodel (which I am reluctant to advise) you will need to change it to a "case" statement, you cant just layer up additional "if()"s.

 

case(action="File quarantined","blocked", isnull(action) OR action="","unknown", 1=1, action)

 

If my comment helps, please give it a thumbs up!

try changing it to 

 

if(action="File quarantined","blocked",action)

 

That looks to me like the intent is to re-write the action to be "blocked" for a quarantine message, otherwise leave action as it was

if (action = quarantine, re-write it as action="blocked", otherwise set action=action( i.e whatever it already was) )

I appreciate the reply, unfortunately it did not work. There are 2 eval expressions seen as below. Does there need to be something in between? Thank you !

if(isnull(action) OR action="","unknown",action)
if(act="File quarantined","blocked",action)
