Hello,  
Every time I try to create a new Rollup column by calculating the “SUM” the system crashes, the new column is not created and I need to restart Glide …  
The column has 2970 rows.  
Could it be something with memory?  
How can I solve this?

Hi Mark, sure, here is the app: [https://app.capitalizados.com/](https://app.capitalizados.com/)  
I will try to explaim better:

- Column 3 - Math. An average between Col1 and Col2
- Column 4 - (my objective) Rollup by calculating the SUM of Col3

When I try to create this Column 4 (everytime) my app crashes and I have to restart the Glide…
