Macro/Function question???

Hello,

i am currently making a spreadsheet that will log our equipment that is being repaired and have had some luck using the IF statement in the VB side of it.
i have a drop down list with the equipment in it and when a piece of equipment is selected the script puts the part number into a different cell.

my problem is that, as there is going to be lots of different items entered in to be repaired, the code will be very long winded. i was wondering if there was a shorter way of doing things or if there is actually a preset function already in excel that could do this task.

below is a copy of the code currently doing the task. this is only for 2 items so far to be entered from a possible drop down list of 11 different types of equipment.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

If Range("C5").Value = "equip1" Then Range("D5").Value = Range("K7").Value
If Range("C5").Value = "equip2" Then Range("D5").Value = Range("K8").Value
If Range("C5").Value = "equip3" Then Range("D5").Value = Range("K9").Value
If Range("C5").Value = "equip4" Then Range("D5").Value = Range("K10").Value
If Range("C5").Value = "equip5" Then Range("D5").Value = Range("K11").Value
If Range("C5").Value = "equip6" Then Range("D5").Value = Range("K12").Value
If Range("C5").Value = "equip7" Then Range("D5").Value = Range("K13").Value
If Range("C5").Value = "equip8" Then Range("D5").Value = Range("K14").Value
If Range("C5").Value = "equip9" Then Range("D5").Value = Range("K15").Value
If Range("C5").Value = "equip10" Then Range("D5").Value = Range("K16").Value
If Range("C5").Value = "equip11" Then Range("D5").Value = Range("K17").Value
If Range("C5").Value = "" Then Range("D5").Value = ""

If Range("C6").Value = "equip1" Then Range("D6").Value = Range("K7").Value
If Range("C6").Value = "equip2" Then Range("D6").Value = Range("K8").Value
If Range("C6").Value = "equip3" Then Range("D6").Value = Range("K9").Value
If Range("C6").Value = "equip4" Then Range("D6").Value = Range("K10").Value
If Range("C6").Value = "equip5" Then Range("D6").Value = Range("K11").Value
If Range("C6").Value = "equip6" Then Range("D6").Value = Range("K12").Value
If Range("C6").Value = "equip7" Then Range("D6").Value = Range("K13").Value
If Range("C6").Value = "equip8" Then Range("D6").Value = Range("K14").Value
If Range("C6").Value = "equip9" Then Range("D6").Value = Range("K15").Value
If Range("C6").Value = "equip10" Then Range("D6").Value = Range("K16").Value
If Range("C6").Value = "equip11" Then Range("D6").Value = Range("K17").Value
If Range("C6").Value = "" Then Range("D6").Value = ""

End Sub

any ideas?
Cheers,

Nick
