I’ve been using Tiller since about October and loving it. I’m really just using it for basic expense/category tracking at the moment, but plant to start using the budgeting features in the future.
I recently purchased a car, and created a category “Car purchase” to track all of the expenses related to it. Everything was fine until just a few days ago, when I attempt to use that category, I get the attached error message (“The data you entered in cell D24 violates the data validation rules set on this cell”). I’ve previously used this category with no issue.
I also noticed that another category is causing the same error: “Auto maintenance”. It seems that all of my other categories are still working correctly (although I’ll admit I didn’t take the time to test every category). I’ve also previously used this category with no issue.
To my knowledge, I’ve made no changes to my sheet, just importing transactions and categorizing them appropriately.
Does anyone know what might be causing this error? I tried searching the community but couldn’t find any threads with the same problem.
