Im search by phone number but if im using for example Lookup Column from A to H collums its all good,
but then im using it futher im getting Internal server error message, its because of check boxes true or false?

Hey @Ernestas

We would recommend you to use "Lookup Values V1" for your current use case. Kindly try that out and let us know if in case you face any further issues.
