SharePoint Online Column Calculation

[Silas_Muth]

Hello,
I have created 2 lists on my SharePoint Online page.
In the 2nd list I created a LookUp column to a number column from the 1st list.
Now I want to create a calculated column in the 2. list, in which one column is calculated with the LookUp column.
I always get the error message that he can not find the columns.
Is there a workaround how to solve this?

Thank you very much and best regards
Silas Muth

@Silas_Muth , Lookup columns are not supported in Calculated column formulas.

Workaround: You need to create a Power Automate flow (or designer workflow). Run the workflow on item create and item update. In workflow you can update the column in list 2 with the number value from your lookup column.
