I have created a shapefile and want to label this. I order to do this I need to add a field in the attribute table and give the file a name. I have managed to add the field in the attribute table and am in editing mode. For some reason It will not let me type into the empty cell, I have also ensure that the field type is 'text'. I tried it out on the attribute table on a data point and it worked fine, it seems to be an issue with only shapefiles which is strange as I know I have edited these in the past.
Does anyone know what might be wrong?
