Within the macro syntax, $(varname)$ expands values that are defined in variables **outside the macro definition** (i.e., using <$set> or <$vars>) and $varname$ expands values that are **passed as arguments** to the macro call. To reference a variable that has been **defined within the current scope** (i.e., the "fieldName" variable defined by the <$list> widget) you need to use the <<varName>> syntax. However, because you are passing <<varName>> as a parameter to another macro, you can't just use <<varName>> because the <<...>> syntax doesn't "nest". Thus, the following macro syntax does NOT work: <<FieldThing <<fieldName>>>> Fortunately, there is an alternative *widget* syntax for making a macro call, that does allow you to use the <<...>> syntax to specify parameters: <$macrocall $name="FieldThing" name=<<fieldName>> /> That should do it. Let me know how it goes. enjoy, -e Eric Shulman TiddlyTools.com: "Small Tools for Big Ideas" (tm) InsideTiddlyWiki: The Missing Manuals -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
