One quick note: subtiddlers are a completely different thing in tiddlywiki and using sub tiddler in the way you are is going to get very confusing when asking for help. Transcluded tiddler or just tiddler would work in this context and not cause confusion for the people answering your questions.
You are describing templates, so the good news that what you want to do is possible. The biggest problem I see people having with this is conceptual. To do what you want to do make a tiddler called SomeTemplate and put this in the text field: Capital: {{!!capital}} then in the tiddler you want it displayed in put {{||SomeTemplate}} That should display Capital: London in the UK tiddler you described. But in this form it isn't very useful. Depending on context you probably want to either use view templates or to create a viewer tiddler that will display the content of your other tiddlers using the templates you want. I have some things about templates here http://inmysocks.tiddlyspot.com/#Templates%20in%20WikiText it isn't very complete but it does have some examples you can look at. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
