I want to make progress bar in first database, that show, how many questions from each subject i have as Status To-do/ In Progress/ Complete in second database. I have relation, where i linked all questions to one subject and in second database i have linked all subjects to each question, that they belong to. Now i dont know, how to make the progress bar, I want to have 3 columns with progress bars in first database, that will show me, how many % of questions i have as To-do/ In progress/ Complete as status in second database. To-do/In progress/Complete together is 100% of questions, how can i do that?
