It's difficult to tell from the screen shot, but check that 'find' has the correct label; an incorrect label will result in the error message you see. 

I've typed it in to my Prime 3.1 and it seems to work OK.  If find's label is correct, please post your worksheet so that somebody can have a look at what's actually there to see what the problem is.

You can only use find within a  solve block.
