**kbaudelin**Another question, would it be possible to stopped calculation when it would be 50 (for example) and begin another field calculation starting from 0 and when it would be 50 (always for example), begin another field calculation ?

For explain that we need, we can have 1, 2 or 3 buses for 50, 100, 150 students and we would like just have one list, checked students and when the first bus is full, stopped the first calculation and passed to the second calculation starting form 0, and so on.

**Chriistian**Hi,

Are you referring to this form - http://www.jotformpro.com/form/51864555616968? If I understand your concern correctly, this is possible using conditions. I have created a sample demo form, can you check this form - http://www.jotform.com/53283351702955 if this is the logic you want to implement on your form? If you are referring to a different concern, can you provide us more details so we can further check?

Regards.
