Hi Tuck, I assume this is the input that works? <input type="number" STYLE="color: #1C2833; font-family: Verdana; font-size: 12px; background-color: #F9EBEA;" name="attr_SkillRatingBody" value="@{Body} + @{SkillTitleBody}" disabled> What is the input that isn't working exactly? If it's another html auto-calculated attribute, can you successfully get values of each component attribute on their own. ie call each component-attribute in chat and get the current value. side-note (probably unrelated to this problem, but...) I saw a couple oddities in the code that I'll mention. <input type="hidden" name="attr_expspent" value="@{skilltitlebody + 1} + @{skilltitlemind + 1} + @{skilltitleeq + 1} + @{skilltitlequick + 1}"> Seems like those attribute names are most likely malformed and should actually be... <input type="hidden" name="attr_expspent" value="@{skilltitlebody} + 1 + @{skilltitlemind} + 1 + @{skilltitleeq} + 1 + @{skilltitlequick} + 1"> and something else that caught my eye; <td bgcolor="#F5B7B1"> <!--input type="number" STYLE="color: #1C2833; font-family: Verdana; font-size: 12px; background-color: #F9EBEA;" name="attr_SkillProgressBody" value="0" min="0"--> </td> <td bgcolor="#F5B7B1"> <!--input type="number" STYLE="color: #1C2833; font-family: Verdana; font-size: 12px; background-color: #F9EBEA;" name="attr_SkillProgressMax" value="(@{SkillTitleBody} + 1) * 10" disabled--> </td> The commented out code is "odd" to me. As-in, comments used to nullify code should wrap the actual code and not be part of it. <td bgcolor="#F5B7B1"> <!-- <input type="number" STYLE="color: #1C2833; font-family: Verdana; font-size: 12px; background-color: #F9EBEA;" name="attr_SkillProgressBody" value="0" min="0"> --> </td> <td bgcolor="#F5B7B1"> <!-- <input type="number" STYLE="color: #1C2833; font-family: Verdana; font-size: 12px; background-color: #F9EBEA;" name="attr_SkillProgressMax" value="(@{SkillTitleBody} + 1) * 10" disabled> --> </td> Technically, both accomplish the same thing in this example, but I've never seen it done quite like that and I could see how this could easily lead to breaking the html if/when it was ever un-commented. Just thought I should mention it. This was just in the immediate vicinity of your SkillRatingBody attribute. I'm totally not meaning to be a coding gatekeeper here. lol ;-)
