Hi, I have a form that has four groups with the same questions, but on a different theme. Most of the each theme’s form is a long matrix. I have built the form for each group/theme separately and they all work well. Now I am trying to put them all in a single form and am getting this error message when I try to edit the XLSform in the formbuilder in order to change to the form style to “grid theme” in “Layout & Settings” before I try to visualize it. The form is huge – over 5000 lines, each one appearing as a question. I have renamed group tags in the different groups/themes.
What could the problem(s) be, any suggestions? I saw a previous question about the same type of error, that had been resolved with better internet connection, but that has not helped me (yet?).
Thanks for the quick reply!
The matrices are not exactly the same. The names on the rows are fixed and required. The two first columns are the same for the four matrices, but one has only three questions, the other have four questions and the there are variations in the questions. But I will follow all your suggestions. As I mentioned earlier, I am new to KoBo and it seems I started with a tough job!
