**kyrglypt**Hello,

I have included in my form a Multi-line Question, part of which is number (%).

So, participants will have to include a criterion and then a weighting factor.

I would like to include a conditional where if the sum of all weighting factors is different to 100, then the form could not be submitted.

However, I could only find how to apply conditionals in individual responses/values and not to a combination of them (sum in my case). Is there any other way I could do that?

Many thanks in advance for your response.

K.

**John_Benson**I checked the last form you edited and the form was not found.

Could you please provide the form link where you need assistance so we can check it further?

I think we can use the Show/Hide condition to hide the Submit button if the condition is met. Here's a guide: https://www.jotform.com/help/316-How-to-Show-or-Hide-Fields-Base-on-User-s-Answer

**kyrglypt**Hi there,

The link is: https://form.jotformeu.com/80687535384367

Can you access it now?

The idea is that in Question 3: Peer Assessment Criteria to embed a conditional that all weighting factors need to sum up at 100%. So, I would like the sum of: Peer Assessment Criterion 1 Weighting Factor + Peer Assessment 2 Criterion WF + PA 3 WF+ PA 4 WF to be equal to 100%, otherwise the participant can not proceed with the submission.

Would something like this be possible?

For now, I can only embed conditionals in only individual cases… and even so, it seems that I can not disable the submission.

Hope it is clearer now.

Many thanks in advance,

K.

**BDAVID**I just cloned your form, and it only has two fields in it, and no conditions or anything else, that would give us a clearer idea of what you are trying to do:
