Try this;
=IF(B13=DATEVALUE("Jun-08"),C13,0)
You have two probable issues;
1. Data type mismatch. Your formula compares a text string ("Jun-08")
to a date. Dates are actually stored as numbers (8-Jun-2008) = 39607,
so effectively you're saying "if that basket holds 10 apples, then do
this" but the basket only ever holds pears.
The DateValue function included in my example effectively converts
pears to apples (text to a date number) in order to make a valid
comparison.
2. It isn't clear which date in June you mean - you probably mean the
entire month. Even though you have specified the format in B13 to
show only mmm-yy, it must, if it is truly date formatted, have a day.
If you have not specified a day, it has probably defaulted to 1/6/08,
which should work with the formula above. It works for me.
If you did specify a day, and it was not the first, set it to the
first.
It should work then.
There are more complicated methods which pull out only the name of the
month and then use it for comparison, but this is the simplest thing I
can think of that meets what I can see of your requirements.
Most importantly, play with it until you understand it or it will be
easy to make a similar error. Do some experiments.
Here is a copy of the Help file's contents for DateValue;
DATEVALUE
See Also
Returns the serial number of the date represented by date_text. Use
DATEVALUE to convert a date represented by text to a serial number.
Syntax
DATEVALUE(date_text)
Date_text is text that represents a date in a Microsoft Excel date
format. For example, "1/30/2008" or "30-Jan-2008" are text strings
within quotation marks that represent dates. Using the default date
system in Excel for Windows, date_text must represent a date from
January 1, 1900, to December 31, 9999. Using the default date system
in Excel for the Macintosh, date_text must represent a date from
January 1, 1904, to December 31, 9999. DATEVALUE returns the #VALUE!
error value if date_text is out of this range.
If the year portion of date_text is omitted, DATEVALUE uses the
current year from your computer's built-in clock. Time information in
date_text is ignored.
Remarks
Excel stores dates as sequential serial numbers so they can be used in
calculations. By default, January 1, 1900 is serial number 1, and
January 1, 2008 is serial number 39448 because it is 39,448 days after
January 1, 1900. Excel for the Macintosh uses a different date system
as its default.
Most functions automatically convert date values to serial numbers.
