Finding an intersection

I have a chart with values in column A and Values in Row 1... I need for users to be able to enter in a value to look up in column A and another to look up in Row 1 and the value that is in the cell where the intersection occurrs... I've tried indx and indx match, but am new to excel, and just can't seem to make it work... help would be greatly appreciated!!! I'm attaching the spreadsheet so that you can look at it... The Rating tab is where the users need to be able to enter in values for Baseline and Actual and then the "rating" box is where I need the intersection cell value to appear...
