Thanks Saxy. Think I may be worrying too much. I can do most of the basics, including formulas, but because I don't use much, if at all for the last few years, I may need a bit more thinking time than somebody using it on a daily basis.
Yelenots, good luck to you. The course I've been doing online is excellent and assumes you know nothing. Once I had the nouse to open the course AND the workbooks on screen at the same time, it got a lot quicker. Here's the link if you're interested.
