If cell equals text then cell returns text from another cell

[Beckslad]

Hi,

i am am trying to return the value of a cell if another cell equals text

for example in cell a1, if cell b1 = 'yes' then return the data in cell c1 into cell a1
if that makes sense?

thanks in advance

In cell A1:

=IF(B1="yes",C1,"")
