<br>
My apologies to both you and Matt as I should have been clearer. My aim is to merge them both so that I can use this shapefile in another piece of software (which will only accept one shapefile to be viewed at a time). However, what you are both suggesting
does work perfectly if I want to stay in QGIS, so thanks very much for your help!<br>
