Import specific cells from a user chosen spreadsheet

Hi, I need some help. I need to import some spreadsheets that are sent to me into a master database spreadsheet. I have attached both below. The complaintstest.xls is the master database and the other is the sheet that will be imported. What I would like to happen is when the macro is run, the user will be able to select the sheet they would like to import through a dialog box. After the sheet is selected the macro will import the cells from the selected sheet into the master database in a particular order. In the master database example on row 2 I have listed the columns from the sheet to be imported in the corresponding column on the database sheet. This will macro will be run a couple of times a week so the macro will have to find the next empty row to start the import on. If you have any questions, please let me know!

Thanks!
