I am trying to run the query shown below to include the results in a report and am getting an `Operand should contain 1 column` error #1241. I have not been able to figure out the cause of this. If I run this part by itself I do not get any errors: `(pct_return_1 * .25) + (pct_return_2 * .25) + (pct_return_3 * .15) + (pct_return_4 * .15) + (pct_return_5 * .2)`

Here is the code: 

```
DROP TABLE IF EXISTS temp_5;
CREATE TABLE temp_5 (
    date_value date default NULL,
    pct_return_portfolio double default NULL,
    pct_return_benchmark double default NULL);

INSERT INTO temp_5 (date_value, pct_return_portfolio, pct_return_benchmark)
SELECT
 (date_value,
  (pct_return_1 * .25) +
  (pct_return_2 * .25) +
  (pct_return_3 * .15) +
  (pct_return_4 * .15) +
  (pct_return_5 * .2)
  FROM Temp_4),
pct_return_6)
FROM temp_4;

```
