Tank you. I did have a look at this previously, but just ended up confusing myself I think, with what code to ad to button, and what to put into the custom.js file, and so forth.
I tried so many different options, that I just mumbled it all, and gave up after umpteenth sends to my phone to test out.
But I will try again, just thought someone might have already done a simple version 🙂
Again though , thank you 🙂
