Thanks for the prompt reply! As you correctly surmise I am comfortable with some "simple" programming... but I can't get your script to come back with any result (and I have tried several variations - and I did have the plugin already installed).
Perhaps I should give a bit more detail: The tiddlers all have different titles but the same tag. There are actually 5 different fields in each tiddler containing a value (time in minutes). So basically, all I need for my original attempt to work is to know how many tiddlers have that specific tag.
