Connected Evaluation form - Automatic calculation

I would like to build a connected Evaluation form

What I mean by that is, if the user either enters numbers (scale of 1-5, or 1-10), or if they use the sliding scale, I would like these connected to automatically calculate the remaining value for the other values.

So if there is a total of 10 points, by selecting 3 for the first selection, they only have 7 points left. If the next selection is 2, they only have 5 left until it is depleted and they cannot make more selections.
Using a slider, if the first selection is 10 and they start dragging the second slider to 5, the first slider will automatically reduce in value.

Separte to this, I also want to know if it's possible to remove a selected value.
If the user must rank something on the scale of 1-5, ensuring that they can only enter 5 once, or 4 once.

Thanks, 

You may perform calculations and get a total based on all the selected options on your form, please check the following guides that will help you with that:

Now, regarding the unique selections, the only way that I think you may compare the value for all the fields is through conditions, you will find more information about it here:  https://www.jotform.com/help/57-Smart-Forms-Using-Conditional-Logic 

For example, you may use a show/hide condition and if there is more than one similar value then you may show  a text element indicating that options must be different. 

I hope this helps.
