Connecting two points to line in kobo ToolBox

[Kal_Lam]

Welcome to the community, @yeshi_2021! Maybe this post discussed previously should help you solve your issue:

Pull GPS points taken in real-time into a mapped geoshape

Thanks @Xiphware, It was the space really! But concat(" ", ${location2}, “;”, ${location3}, “;”, ${location4}, “;”, ${location5}, “;”, ${location2}) would not work. As probably the leading blank is cut-off by the parsing. So, here the corrected version. @rratnaya polygon test 04.xlsx (18.6 KB) I only could test it with Online validator Preview, as the “detect current location” didn’t work in KoBo Preview. But this is another issue. Have a nice week-end
