Thankful for any help.
My database has 10 Vehicles. Each Vehicle row is described by a Date and a Price.
I try to chart with Bubble Charts plug-in. But receives an error message that says: a value expression should be number but right now it is a list of numbers?
My setup is in pics below. Appreciate any help or guidance.
The error occurs because the Value Expression expects a single number, but your setup provides a list of numbers.
Quick Fix: Change the Value Expression to:
Current's Vehicle's Price:first item
This extracts a single value to plot on the chart.
Best Practice: Update your database structure to ensure the “Price” field is a single value (not a list). This avoids confusion and ensures the chart works seamlessly.
Let me know if you need further help adjusting the setup!

I changed it to a text (and not a list) and it works now.
