Cells() takes Row and column as params, not a cell ref
- you need:
Range("B4")
or
Cells (4,2)
instead of
Cells("B4")

A cell has the value=0.023. The Category is chosen as 'General' for
this cell.

I want to get the inverse of that cell value i.e. 0.023, and ignore the
decimal point in the result.

1/0.023 = 43.478 = 43

Here is the excerpt from the macro:
Line1 oneRequestTime = 1 / Worksheets("Banking").Cells("B4").Value
Line2 Application.WorksheetFunction.Floor(oneRequestTime , 1)

But, the 'Type mismatch' error is reported at the Line1. How do I get
rid of this error. I tried to declare 'oneRequestTime' with different
types. But, it did not help!
