Hi all... I'm working on a sheet for Eclipse Phase. I'm trying to set up the skills so they add the proper attribute base to the skill. This involves the base attribute and a bonus provided by the morph in use and adding to the skill points to get a skill total. In practice, for the Cognition Attribute , I have one line to set the base value: <input name="attr_ cog " value="15" type="number"> A second line in another area sets the morph bonus: <input name="attr_ morph_cog " value="0" type="number"> A third line in another area shows the Attribute total: <input type="number" name="attr_ Tcog " value="@{ cog }+@{ morph_cog }" disabled="true"> All of this works fine in the sheet. The third line auto-calculates as expected. The problem I'm having is using Tcog , or even @{ cog }+@{ morph_cog }, again when I want to add that to a skill value. I ask for a value for the Animal Handling skill here: <input type="number" name="attr_ Skill01 " value="0" > Animal Handling I want to show the actual skill roll, which would be Skill01 + Tcog : <input type="number" value="@{ Tcog }+@{ Skill01 }" disabled="true"> The result of that formula is a blank text input box. I can change the formula, and still get the same result. Only if I give the value an actual number do I see anything. I don't know if I'm running into the limitations of the system or my own mind. Any suggestions would be deeply appreciated! Michael
