This is most likely just a mismatch between the course material and the Mendix version you’re using. In older versions or screenshots, the page may have contained two editable data grids, so one of them was referred to as grid2, but in your current project there’s only a single editable data grid, which is why you only see grid1. The important thing is to follow the intention of the step, not the exact widget name, so you can safely apply the instruction to the existing editable data grid and continue. If later steps still mention grid2, just treat that as “the editable data grid on the page,” or, if you prefer to match the tutorial exactly, you can simply rename grid1 to grid2 since the name itself doesn’t affect the behavior.
