Division by two on autocalculated field

In my custom character sheet I have a field that contains the total encumbarance of the character (addition of armor and shield encumbarance and general encumbarance) - this is an autocalculated field. Now I want to subtract this value from certain skills (which works fine) and half the encumbarance (rounded up) from the speed of the character. This is where I run into problems. I have the following set as value for my "speed" field in the character sheet: value="@{gk_value}+@{bew_value}+@{gsw_mod}+@{gsw_temp}-ceil(@{combat_beh}/2)" everything works fine, except for the last part. the value of the field "combat_beh" (which is the combined total encumbarance) is not divided by 2 but instead subtracted completely. I tried with extra () around the @{combat_beh } /2 already, and tried to reverse the order of the values etc. Am I missing something?

Did you try ceil((@{combat_beh}) / 2) ? (Or putting the parentheses in the value of combat_beh.) The autocalc system works by essentially copying and pasting the value of each attribute into its @{attr} reference, and repeating until there are no more attribute references. So, for example, something like this: <input type="number" name="attr_a" value="3"> <input type="number" name="attr_b" value="1"> <input type="number" name="attr_c" value="@{a} + @{b}" disabled> <input type="number" name="attr_d" value="ceil(@{c} / 2" disabled> Would essentially result in @{d} being "ceil(3 + 1 / 2)". Apply order of operations, and you get ceil(3 + 0.5), ceil(3.5), 4. If @{c} were instead "(@{a} + @{b})", or if @{d} were "ceil((@{c}) / 2)", the process would be ceil((3 + 1) / 2) -> ceil(4 / 2) -> ceil(2) -> 2.

No, I did not try that. With your explanation I get it, though, including why I had always the full value beeing subtracted... The combined total was a+b , and the character I tested it with had b = 0, while I only ever changed a around. That fixes it, thank you!
