How to create a new field as Metric?

I have three metrics. "cost%" is generated by “cost" comparison calculation.

Now I want to add a new field to multiply "cost%" by "ROI".

How should I write the formula? GPT can't solve my problem.....

Hi @Janice414 

If you generated the cost% either as stated in the documentation or as a percent column, you can refer to both in the field picker. This allows you to calculate new metrics for ROI multiplied by cost% as a table calculation.

I hope this helps you.
