In Excel - how do you get rid of the red triangle ?

[KatyMac]

I think it means you put a note there (but I didn't)

& it won't let me 'undo'

How do I make it go away

TIA

Right click, delete comment???

There isn't any comment there it's a blank box (with my name & a colon)

Sorry - I'm with you now

Sorted thanks
