Excel / Physics problem

  1. Nov 24, 2011 #1
    I'm having a problem with a Physics / Excel sheet I've been working on.

    Does anyone here think they might have the Excel expertise to help?

    It's not very advanced Excel. Get in touch immediately please if you do.

    Thanks

    It used to be possible to contact a poster directly via e-mail, without posting to this public forum, but that facility seems to have been removed (at least in the menus I have access to). Therefore, you must now post your explicit question here.

    I think you can still PM.

    It's square root of a negative number in the Excel sheet I'm having trouble with.

    That's kind of vague. Are you trying to compute the square root of a negative number in Excel, and you don't know how? Or are you trying to compute the square root of a number that is supposed to be positive but is turning out negative, and hence messing things up?

    Yes. I've just realised about the time I posted that that's what's wrong with my Excel sheet. I'm looking at Tutorials online but can't seem to figure out exactly what's going wrong.

    On my machine, I no longer get menus allowing me to send PMs.

    What do you see when you click on a posters name to the top left of their message?
