Help with Tabs/fieldsets

I am currently trying to make a tab system for my character sheet, and copied the tab code directly from the roll20 tab example on the css wizardry wiki page but it shows a blank screen when I click away from the first tab.  I think it may have something to do with a dropdown in one of the tabs thats not showing, but Im not sure, here is the css I think is causing problems /* By deafult, hides all archetypes*/ .charsheet .sheet-winded, .charsheet .sheet-dizzy, .charsheet .sheet-groggy, .charsheet .sheet-disoriented, .charsheet .sheet-nauseous, .charsheet .sheet-blurred_vision, .charsheet .sheet-ringing_ears, .charsheet .sheet-vertigo, .charsheet .sheet-tunnel_vision, .charsheet .sheet-flash_blindness, .charsheet .sheet-shivering, .charsheet .sheet-slurred_speech, .charsheet .sheet-weak_knees, .charsheet .sheet-cold_sweats, .charsheet .sheet-confusion {     display: none; } /* Show elements based on input value */ .charsheet .sheet-injurytoggle[value="winded"] ~ div.sheet-winded, .charsheet .sheet-injurytoggle[value="dizzy"] ~ div.sheet-dizzy, .charsheet .sheet-injurytoggle[value="groggy"] ~ div.sheet-groggy, .charsheet .sheet-injurytoggle[value="disoriented"] ~ div.sheet-disoriented, .charsheet .sheet-injurytoggle[value="nauseous"] ~ div.sheet-nauseous, .charsheet .sheet-injurytoggle[value="blurred_vision"] ~ div.sheet-blurred_vision, .charsheet .sheet-injurytoggle[value="ringing_ears"] ~ div.sheet-ringing_ears, .charsheet .sheet-injurytoggle[value="vertigo"] ~ div.sheet-vertigo, .charsheet .sheet-injurytoggle[value="tunnel_vision"] ~ div.sheet-tunnel_vision, .charsheet .sheet-injurytoggle[value="flash_blindness"] ~ div.sheet-flash_blindness, .charsheet .sheet-injurytoggle[value="shivering"] ~ div.sheet-shivering, .charsheet .sheet-injurytoggle[value="slurred_speech"] ~ div.sheet-slurred_speech, .charsheet .sheet-injurytoggle[value="weak_knees"] ~ div.sheet-weak_knees, .charsheet .sheet-injurytoggle[value="cold_sweats"] ~ div.sheet-cold_sweats, .charsheet .sheet-injurytoggle[value="confusion"] ~ div.sheet-confusion {     display: block; } /* configure the tab buttons */ .charsheet .sheet-character, .charsheet .sheet-journal, .charsheet .sheet-configuration {     display: none; } /* style the active button */ .charsheet .sheet-tabstoggle[value="character"] ~ div .sheet-button0 {outline: 2px solid red;} .charsheet .sheet-tabstoggle[value="journal"] ~ div .sheet-button1 {outline: 2px solid red;} .charsheet .sheet-tabstoggle[value="configuration"] ~ div .sheet-button2 {outline: 2px solid red;} /* show the selected tab */ .charsheet .sheet-tabstoggle[value="character"] ~ div.sheet-character, .charsheet .sheet-tabstoggle[value="journal"] ~ div.sheet-journal, .charsheet .sheet-tabstoggle[value="configuration"] ~ div.sheet-configuration {     display: block; } As for field sets, as you can see above there is an injury's part with a dropdown.  I'm trying to have a field set where the injury's can all be shown and selected, but I'm doing a script to auto do the math for the injury's for the rolls, and they stop working when I place it in the fieldset, here is the basis of the code below with an example injury choice.  Any advice would help <h2>Injurys/status</h2> <div class="3colrow"> <div class="col"> <label class="txt" style="font-size:1.8em;text-decoration:underline;">injurys</label> <input type="hidden"  <select name="attr_injury"> <option disabled

Try copying the code exctly from that sheet, then modify it a bit at a time to fit your sheet.
