Hi guys, In my work we have to send texts to people through emails. The format needs to be +447123456789@sms.com (as an example). I have an HTML page with some helpful notes, links etc I keep open for quickness. What I want is to have a textbox on the page that I can type a standard mobile number into as '07123456789' and a copy button under it that will copy it as +447123456789@sms.com. So it needs to replace the '0' with '+44' and add the '@sms.com' on the end. I have seen it done before but can't figure out how. I know basic coding but I am better at tearing apart and rearranging to make it how I want than writing from scratch. Might be something really simple but I am just missing it! Any help would be much appreciated! Thanks
