Hello I have length 120 m. I have to divide this section by 5. But I want dynamically change each section. For instance if the first section 50 m, then the rest 70 m would be divided by 4. Same for second section is 10 m then the rest 60 m would be divided by 3. But I have a problem in my concept setup the summation of each division crossed 120 if I change manually any middle section like 80 m. Then we can't control the division. And my formula setup can't control previous division. But I want to control each division dynamically. Not from first to last. Is there any process I can achieve this? Please help me out.
