I'm not so sure I understand this, resolve being 3 and composure being 3 would be a total of 6. If this is what you were trying to achieve and you wanted willpower to fill in 6 circles, that currently can't be done. If you just wanted a textbox to show the total you can do that like this:
Yes you are understand my question. I taked on error key (5 vs 6).
I'm desolate it's not possible I will take your proposition.


Your method for find the smaller number is very creative. Thanks for your work. but there is an error.
You would then have two numbers, one will be zero and one will be a positive number. Now create two more number controls that will turn the negative number into a 1.
...
Now lets look at the code at work:
Let's say Dex is 2 and Wits is 5.
DexMinusWits would be -3
WitsMinusDex would be 3
The DexIsLower number control would multiply -3 times 0 which would be 0
The WitsIsLower number control would multiply 3 times 1 which would be 3
The DexMultiplier number control would be set to 1 by the valuemap
The WitsMultiplier number control would be set to 0 by the valuemap
The DexFinal would add Dex of 2 and then multiply it by DexMultiplier of 1 and give you a total of 2
The WitsFinal would add Wits of 5 and then multiply it by DexMultiplier of 0 and give you a total of 0
The Defense would add DexFinal of 2 to WitsFinal of 0 and give you a Defense of 2 (which is what was the lower of the two numbers)
Is not possible.
The numbercontrol "DexIsLower" and "WitsIsLower" transform the negative number to zero and keep the positive number. The numbercontrol "DexMultiplier" can't operate if there 're not multiplied by 1.

Look the solution.

- Suppress the numbercontrol "DexIsLower" and "WitsIsLower".
- Change the source by "DexMinusWits" in the numbercontrol "DexMultplier" and replace the valuemap. "-5:1,-4:1,-3:1,-2:1,-1:1,0:0,1:0,2:0,3:0,4:0,5:0"
- Change the source by "WitsMinusDex" in the numbercontrol "WitsMultiplier" and modifie the valuemap. "-5:1,-4:1,-3:1,-2:1,-1:1,0:1,1:0,2:0,3:0,4:0,5:0"
Code:
 <numbercontrol name="DexMultiplier"> 
            <invisible /> 
            <source name="DexMinusWits" op="+" valuemap="-5&#58;1,-4&#58;1,-3&#58;1,-2&#58;1,-1&#58;1,0&#58;0,1&#58;0,2&#58;0,3&#58;0,4&#58;0,5&#58;0" /> 
        </numbercontrol> 

        <numbercontrol name="WitsMultiplier"> 
            <invisible /> 
            <source name="WitsMinusDex" op="+" valuemap="-5&#58;1,-4&#58;1,-3&#58;1,-2&#58;1,-1&#58;1,0&#58;1,1&#58;0,2&#58;0,3&#58;0,4&#58;0,5&#58;0" /> 
         </numbercontrol>
For exemple:
dex = 2
wits = 5
dexminuswits = 2-5 = -3
witsminusdex = 5-2 = 3
dexmultiplier = dexminuswits (valuemap "-3:1") = 1
witsmultiplier = witsminusdex (valuemap "3:0") = 0
dexfinal = dex * dexmultiplier = 2 * 1 = 2
witsfinal = wits * witsmultiplier = 5 * 0 = 0
defense = dexfinal + witsfinal = 2

Look the complet code.
