I need some assistance with how to write an Excel formula for the below:

In cell `A28`

one of the following will be entered: LIN, LOX, LAR, CO2, GH2, GN2 or GO2

Depending on which is entered in cell A28 will have a conversion value that needs to be multiplied by the value in cell D63 and that product to be placed in cell S63

Example:

IF A28=LIN,

THEN CELL D63 NEEDS TO BE MULTIPLIED BY 13.80

AND THAT PRODUCT PLACED IN CELL S63

```
LIN = 13.80
LOX = 12.08
LAR = 9.671
CO2 = 1.0
GH2 =1.0
GN2 = 1.0
GO2 = 1.0
```

Any help is greatly appreciated!
