Copying Formula Issue Advice - I'm SURE there is an easy answer I am overlooking

Hello,

We have a spreadsheet where column A contains a list of properties and columns F thru Y contain summary totals for each of these properties for the year. The first property is on row 3 and I correctly have it pulling over the totals for each category of expense, ie principle, interest, insurance etc. Those expenses are shown by month on a tab with the same name as the property. However, on the property tab, column B lists the expenses and each month is in a column, the sum being in column P for each category of expense. I don't want to have to click in each cell to say ='xxx Carneal'!P12, ='xxx Carneal'!P13 etc. I can copy row 3 down to pull the formula down and get the right summary cell, but doing so pulls down the incorrect tab name. If I copy the formula from the first column over, it gives the correct property tab, but increments by column (D to E for example) instead of moving down rows. I'm sure there is an easy way to do this that I'm overlooking. I would be very grateful if someone could point out the obvious to me! TIA!!!
