Thanks guys.
Robin, im going to try that again, felt as though i followed it word for word, but didn't work as it should for me. Im obviously doing something wrong. Going to try and have another crack later today.
The 3 LED's were lighting up randomly as they should, but the other which is activated by the button on pin 7, was blinking when i pressed the switch, then when i pressed the switch again to turn it off, it stayed on but stopped blinking.
Need to give it a rest for a bit before i try again, thanks for the help
