Hi, the blocks.select function needs a check on line 122 for the mtags variable which can be nil. function blocks.select(state,name,tag,criterium) criterium = criterium or "text" if find(tag,"=",1,true) then tag = "" end local names = settings_to_set(name) local all = tag == "" local tags = not all and settings_to_set(tag) local hide = state == "process" local result = lists.filter { names = "all", criterium = criterium, number = sections.numberatdepth(criterium), -- not needed collected = collected, } for i=1,#result do local ri = result[i] local metadata = ri.metadata if names[metadata.name] then if all then printblock(ri.index,name,ri.data,hide) else local mtags = metadata.tags for tag, sta in next, tags do - if mtags[tag] then + if mtags and mtags[tag] then printblock(ri.index,name,ri.data,hide) break end end end end end end Wolfgang
