Multiple Criteria

Hey Excel Forum Community,

I am in need of some help. I believe this should be an easy fix (well for someone out there), but I can't seem to figure it out. Here what I am looking for. I need to be able see if from Sheet1, the ID numbers in Row 1, appear next to the specific date in Sheet1 column A in the two columns in sheet2 (ex. does ID number 152 (Sheet1 Cell B2) appear on 2/16/2012 from Sheet 2, if it does I want cell B2 on Sheet 1 to say 'Staffed', if it does not appear I want it to say 'Unstaffed'; Does ID number 181 (Sheet1 Cell C2) appear next to 2/16/2012 on Sheet 2 if it does I want 'Staffed' to appear in Sheet1 cell C2, if not I want 'Unstaffed' to appear.). I need to be able to do this for each id number for each date listed on Sheet1.

Also, If the ID number appears multiple times for the same date on Sheet2 I would like to be able to add a column in Sheet1 to show how many times that ID number appears on Sheet2 next to the specified date on . Please advise, I want to learn the formula(s) for both of these solutions I'm looking for but eventually turn this into a Macro.

I hope this all makes sense, if something isn't clear please do not hesitate to ask questions. I look forward to someones help
