[Help] Using select to calculate various dependent values

Hi, I am new to character sheet development and have been looking for a way to exactly determine which value was chosen in a select so that I can use this information to calculate other dependent values. I could not find anything in the help or in the forums, but I might have missed something. So I came up with my own solution which works, but seems rather cumbersome: <select name="attr_Species"> <option value="3">Human</option> <option value="5">Elf</option> <option value="7">Halfelf</option> <option value="11">Dwarf</option> </select> <input style="display:none;" name="attr_species_human" type="number" disabled="true" value="1-ceil((@{Spezies}%3)/100)"/> <input style="display:none;" name="attr_species_elf" type="number" disabled="true" value="1-ceil((@{Spezies}%5)/100)"/> <input style="display:none;" name="attr_species_halfelf" type="number" disabled="true" value="1-ceil((@{Spezies}%7)/100)"/> <input style="display:none;" name="attr_species_dwarf" type="number" disabled="true" value="1-ceil((@{Spezies}%11)/100)"/> Now I can so stuff like the following: <input type="number" disabled="true" name="attr_SK_base_value" value=" -5*(@{species_human})-4*(@{species_elf})-4*(@{species_halfelf})-4*(@{species_dwarf})" /> <input type="number" disabled="true" name="attr_ZK_base_value" value="-5*(@{species_human})-6*(@{species_elf})-6*(@{species_halfelf})-4*(@{species_dwarf})" /> So, my question is: Is there any easier / more natural way to do achieve this? It is fine for 4 species, but I do have cases with a lot longer selects and a way to simplify the process would be greatly appreciated. Thank you and best regards Sönke

I am afraid that you are most probably on the correct track.  As it happens, I was just looking around in here hoping that I could find something better than what I had come up with for the exact same problem, but I don't think there is anything much better than your or my code. Mine looks like the following. <option value="2" title="Movement Rate 14, Karma Modifier 4, Low Light Vision."> Elf</option> <input type="number" name="attr_Race-Elf"        value="(1-(((abs(@{Race}- 2 )+1)-abs(abs(@{Race}- 2 )-1))/2))" disabled /> <input type="number" name="attr_Race-Human" value="(1-(((abs(@{Race}- 3 )+1)-abs(abs(@{Race}- 3 )-1))/2))" disabled /> My formula is based off of         1-min(abs(@{Race}-(whatever)),1)     which will return 1 where @{Race} == (whatever) and zero otherwise. With the Min formula being (((@{x} + @{y}) - abs(@{x} - @{y})) / 2) as has been posted in this forum many times before. The one advantage I see in using the min() formulation rather than your code is that you don't have to assign the values to prime numbers, you can just number them 1 through whatever. You have to replace both the -3's in the code above with the option number you are testing for.  But anyway, no, I don't think there is any easier or more intuitive way of doing this.
