Hi, Robster, welcome to the forum..

As a starter, what is the only number that can go in row 3, column 4? And then row 7 column 5? These are called naked singles and will hopefully help you on your way.

Good luck!

row7 column 5?
then (to use the standard shorthand on this site) r7c4?

There are zillions of helpful people on this site who can direct you to solving techniques from basic to stratospheric. Sadly, I am no good at finding the links but hopefully, someone will be able to direct you. Good luck!
