Modify a excel spread sheet.

Hello, I would like to modify the spread sheet called “OMD vacation spread sheet” but only on the page labeled "OMD OO". The sheet works a job qualification tracker and lets me know how many people with the same job qualification requested vacation on the same date. There is a fixed limit on the amount of people with the same qualification that can be out at the same time. Always have to keep a min amount of people with the same qualification on the job. I uploaded a document has a pic with an explanation. I can also attach another excel spread sheet titled "Pat utilities_Lakefront" to serve as an example of the changes that I need on the particular page on the “OMD vacation” spread sheet. This spread sheet works correctly and its what I need done to the other vacation tracker sheet. I am not sure of the formulas that were used but they should be the same as the “Pat Utilities sheet”. So the “Pat Utilities” sheet works fine and can be used as an example of how the “OMD vacation” sheet needs to work. Its just one page on the OMD vacation spread sheet. I added a red arrow to indicate the sheet that needs to be modified. So basically, I need 4 columns added, and 4 rows added but I am not sure of the formulas used to make them work. The page title also needs to be updated. Let me know please?
