Rollup field error

[Trung_Nguyen]

I would like to have a total of all ordered qty for each item but got this error.

When I use a lookup field, it shows ordered qty correctly.

You have more options in the rollup field. Scroll down to get to them.

If you’ve already seen those options, then please post a screenshot of what you’ve typed there.

Thank you so much. I did not notice there are still options after choosing a linked field.

All done now.
