A formula to populate one cell based on the cell range on another worksheet

I am attaching a workbook with 3 tabs and I am hoping to find help with a formula for cell B2 of worksheet "FTE Requirements".

I would like a formula that will say if A2 (On FTE Requirements Worksheet) is equal to anything in the range of cells A2 - A 13 on worksheet Service Activity Info then cell B2 will equal the amount in column F (Total Hours REquired for Service Activity) in the cell on the same row. I would then copy the formula down to cell B7 so each cell between B2 and B7 would do the same.

So for example on the FTE Requirements Worksheet:
B2 would be 450
B3 would be 170
B4 Would be 3,150
B7 Would be 9,558
All based on the cell range on worksheet Service Activity Info A2:F13

I had some help with a similar formula earlier but this one is on a different worksheet and I can't seem to make it work.

Thanks to anyone that might be able to help me with this one. I am not even sure if it is possible. I am trying to create something that will be very simple for others that do not use excel much at all to use.

Hy there mate,

Try this:
=INDEX('Service Activity Info'!A$2:F$5,Match(A2,'Service Activity Info'!A$2:A$5,0),6)

Put it in cells B2:B7 on the last sheet.

Make sure that the names of service activity are exactly the same....
