0 - 2 of 2 tags for Defined Type name

I get this type of error for below statement:

I'm getting the "SELECT Failed. 3706: Syntax error: Data Type "response_tm_sec" does not match a Defined Type name." error when I run the following SQL on SQL Assistant:
select min(response_tm_sec) min_response_tm
, average(response_tm_sec) avg_response_tm
, max(response_tm_sec) max_response_tm
