Error in User input for dashboard to check a specific IP

[codywsj]

Hi, i am having an error of getting this user input for a drop-down to work where i am unable to find any errors within my code. Can somebody help me for this error?

 This is the error i am getting.

This is my search query

(sourcetype="windows event logs" OR sourcetype="General-linux-sql.log" OR sourcetype="csv")
| eval spec_IP=case ([|search sourcetype="General-linux-sql.log"],
[| rex field=_raw "\[(?<IP_addr>\d+.\d+.\d+.\d+)\]"],
[| search sourcetype="csv"],
[| rex field=_raw ",(?<src_ip>\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}),\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3},,,"],
[| search sourcetype="windows event logs"],
[| search *"Account Locked"*
| rex field=_raw "\[(?<acc_ip>\d+.\d+.\d+.\d+)\]"]
)
| stats count by Specific_IP

That error can happen if one or more of the subsearches returns no results. Check each subsearch to make sure it works by itself - I am suspicious of the "| rex ... " subsearches. Remember that subsearches execute before the main search so they must be valid stand-alone searches.
