Hi Both!
Thanks for your suggestions, I will try them both today and let you know what I found.
I think one of the issues I’m having with it and why I’m a bit doubtful as to weather this will work or not is I have another map that does need a marker.
I guess a way to get this working is use separate code for a map with a marker and one without? This just feels a little ‘hacky’ if you know what I mean?
Thanks, Harry.
