Error: Mismatch between number of collumns on spreadsheet and table schema

[JeffRej_03]

Hello Community, 

My app is not loading successfully because of a mismatch in the number of columns between the spreadsheet and the table schema. According to the error message, the table has 10 columns but the schema has 3 columns. That is untrue, since both the table and the schema have 11 columns. 

I have tried to regenerate the stucture, but the error remains and the app doesn't load. I'm using an app template that I've imported from another Google Account, but it is linked to a new spreadsheet, so there are no problems regarding data usage from different Google Drives. 

Can somebody help me?

Can you show:

1. The error message
2. the AppSheet table
3. The spreadsheet columns

I've just edited the message, now containing the printscreens!

Use the "View Source" button from the "Tables" screen to ensure that your table is based on the spreadsheet that you think it is.
