I'm fiddling with Visual Basic [Excel] and I now don't have my trusty VB
textbook I had in old office and help files aren't installed in this
computer.

What I'm trying to do is have a combobox linked to a cell and then have a
command box I click on and whatever name is in linked cell I'm takien to a
certian cell within spreadsheet eg If A12 = Mike then take me to cell A20.

I canget the IF = bit, but I'm having trouble with 'take me to this cell
bit' and as help files aren't installed here can u have a alook for me on
your PC and let me know? Ta muchly !
