In Excel trying to compare two ranges

select the cell, type in the bar ( above the sheet ) 2003-01-01/2007-01-01
That will be seen as a range by excel

Try using "count if blank"
I am assuming that you need the value to be on sheet 3
If you want the value to be on another sheet, it is more complicated, you will have to "paste special" the value to a different sheet.

You can use IF and ISBLANK. Put this formula on Sheet 1 D1:

=IF(ISBLANK(Sheet3!AM2),"x","")

You can replace "x" by any other value you need.

Below is the formula for "2". The logic should be obvious from this so you can adapt for "1" or a combination of 1 and 2. This need to be written as one long formula so I have pasted it in to this reply so you can do a copy and paste into your spreadsheet. Sorry its not very readable in this form but you could paste into word so you can break it down and examine structure.

=IF(OR((AND(Sheet3!A12="WA",OR(Sheet3!AH2="Lewis",Sheet3!AH2="Pacific",Sheet3!AH2="Wahkiakum"))),(AND(Sheet3!A12="OR",OR(Sheet3!AH2="Clackmas",Sheet3!AH2="Multnomah",Sheet3!AH2="Washington")))),"X"," ")

Well the symbol for greater than would be => and for lesser than would be +<  so if you can incorporate that into your formula it should work. Something like A2=>Sheet3.

You need to change the =IF(AND to =IF(OR
Using AND is saying both conditions must be true. Using OR is saying either condition 1 or 2 need to be true

You were of to a good start. Try using the AND function in the IF Formula as follows:
=IF(AND(Sheet3!H2="Clark College",ISBLANK(Sheet3!I2)),"X"," ")

use VLOOKUP

Use the IF and Date functions together. On sheet 3, put the birthday (3/15/1954) in cell B1, put the beginning date (1/1/1946) in cell C1 and the ending date (12/31/1964) in cell D1.
Then on Sheet 1, but the following formula in the cell you want an X to be placed in.
=IF(AND(Sheet3!B1>=Sheet3!C1,(Sheet3!B1<=Sheet3!D1)),"X"," ").
Make sure you type the formula Exactly as it appears.

Nope, sorry, although I am truly an expert at Excel formulas, I do not understand what you are trying to end up with in the final cell. We can compare a specified field with two spreadsheets - use named ranges and index/match lookup formulas. But then where you really lose me is in reading "a generic field" to find a match, and then placing what "data from another field" into what "other sheet" - ? See the confusion?

Best way to compare 2 given parameters would be to use a nested if formula, with index/match combo. Here is a simple Excel example of how such a formula could be structured:

Sample Data (columnar arangement):
A1: Part B1: Code C1: Price D1: Find Part E1: Find Code
A2: x B2: 11 C2: 5.00 D2: y E2: 12
A3: x B3: 12 C3: 6.00 D3: y E3: 11
A4: y B4: 11 C4: 7.00 D4: x E4: 12
A5: y B5: 12 C5: 8.00 D5: x E5: 11

To retrieve the price for part y with code 12 and return the value to cell F2, type the following formula in cell F2:
=INDEX($C$2:$C$5,MATCH(D2,IF($B$2:$B$5=E2,$A$2:$A$5),0))

Press CTRL+SHIFT+ENTER to enter the formula as an array formula. The formula returns the value 8.00.

To take this one step further, with range names, this example will find one value at a specified location which matches a specific row header value and column header value. Let's say the range is home values (Range=HomeVal), Column A of HomeVal contains street addresses,"row headers" (Range=StAddress), and Row 1 contains dates of the various values that are in the body of the table, "column headers" (Range=Dates). To return the specific value from the range HomeVal to another sheet, where A1=address specified and A2=date specified:
=INDEX(HomeVal,(MATCH($A$1,StAddress,0)),(MATCH($A$2,Dates,0)))

Then make sure to press CTRL+SHIFT+ENTER to enter the formula as an array formula - if you only hit enter, these types of formulas will not work properly.
