When typed directly in cell L11, this formula does what I want:
=IF(E11<0.25,"",E11-TIME(0,16,0))

When I go to the Immediate Window and type ? range ("L11").FormulaR1C1, the
following is returned: =IF(RC[-7]<0.25,"",RC[-7]-TIME(0,16,0))

So I tried to create a procedure using that -

Range("L11").Activate
ActiveCell.FormulaR1C1 = "=IF(RC[-7]<0.25,"",RC[-7]-TIME(0,16,0))"

.... and get the error "Run-time error '1004': Application-defined or
object-defined error"

Can anyone tell me what I am doing wrong?

TIA, Patti
