*Everything else contained inside a macro is returned exactly as defined within the macro.* It is up to the "calling context" to process the returned macro content. When you write: \define artworkurl() <<foldername>><<idcode>><<incremental>><<imagecode>> \define uniqueid() <<idcode>><<incremental>> The results are to simply return the macro's contents as shown. The variables references inside the macros are not automatically converted to their values. If you then *display* the results of the macro, the "<<variablename>>" syntax is automatically "wikified" to render the value stored in the variable. However, when you use the results of the macro as a *parameter* in a $widget, the macro results are passed to the $widget "as-is" without further processing. The easiest way to make your code work (assuming no other problems) is to change these two macros, like this: \define artworkurl() $(foldername)$$(idcode)$$(incremental)$$(imagecode)$ \define uniqueid() $(idcode)$$(incremental)$ By doing this, the content returned from those macros WILL be the *values* of the variables, not the references to the variables. -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
