I'm a complete beginner with Kibana and its my first time creating a scripted field. I'm creating a script to retrieve the transaction id's of dropped transactions from all my transaction logs.

Below is the script which contains an error that I don't understand. It'd be great if someone could explain it to me and provide me with tips for a fix.

\</\>  
string current = "abc";  
for (def log1 : doc['invoice\_id'].values {  
if (log1 != current) {  
log1 = current;  
for (def log2 : doc['invoice\_id'].values) {  
if (log2 == current) {  
if (doc['log\_type'].values.contains("MER\_REQUEST")) {  
if (doc['log\_type'].values.contains("MER\_RESPONSE")) {  
}  
else {  
return current;  
}  
}  
}  
}  
}  
}  
\</\>

I am not sure I understand what you are trying to achieve. Be aware that the scripted field runs in the context of a single document, so you can not compare values from different documents (if that is what you are trying to do).

Oh, I was actually trying to compare values from different logs. Thanks for the help, I'll try to find a workaround. Also, sorry that my question wasn't clear.
