I'm really new to QGIS and GIS software in general. I'm trying make a map travel time across different wards in a city, I have the average travel time and range between peak traffic and lowest traffic. Anyway, I joined the shapefile containing the polygons of each ward to a CSV file containing the above parameters (I joined via name ward 1, ward 2.....so on). I added 2 fields, one fore range and the other for average time (both integer values), i cannot find a pattern as to why only three of these rows merged properly.
The tables have joined, however all but 3 of the cells have a value of null and I cannot figure out why. The cells that do have a clue correlate with the CSV file. I'm properly stuck. Lastly, as I said I'm really new to QGIS and I don't know any code, so I'm sorry I cannot provide that.
