The IF function is used to run a logical test, and react differently depending on whether the result is TRUE or FALSE. The first argument, logical_test, is an expression that returns either TRUE or FALSE.Both value_if_true and value_if_false are optional, but at least one of them must be provided. The result from IF can be a value, a cell reference, or even another formula.

For more information about the new functions, see Statistical functions (reference) and Math and trigonometry functions (reference). If you're using Excel 2007, you'll find these functions in the Statistical or Math & Trig categories on the Formulas tab.

Try saving the file as a macro-enabled workbook (under Save As…). The xls file distributed with version 9.0 sometimes will give false answers depending on the sequence of calculations if multiple xls files are open. Macros in Excel must be enabled to calculate properties. The help file in the REFPROP graphical interface (REFPROP.exe) gives additional information on calculating properties or running macros from any spreadsheet. The REFPROP.xls file can be savedas a template file (REFPROP.xlt). This application calls the Refprop DLL directly rather than through the mex file provided in previous versions of Refprop.
