format of 'if' statement

[ken <gebser mousecar com>]

I'm trying to assign the result of an 'if' statement to a cell... put
this in the cell:

=if(d24>=125000,3650*4d,j30)

but it's rejected ("Invalid expression").

So how to do: "IF d24 is greater-than-or-equal-to 125000, THEN multiply
4d by 3650, ELSE use the value in cell j30".


tnx
