Worksheet / VBA slowdown.. Help Please

[Hemani]

I am a novice user, took a sample Forms sheet from Contexture.com and modified it..
But when I added two Subs to copy data from one sheet to another it slowed down very much.

Code is following:
Sub NewEntryUpdateMaster()
'new entry issued update
Dim issuedlocation As Range
Dim balancelocation As Range

Set issuedlocation = Worksheets("Input").Range("I33")
Set balancelocation = Worksheets("Input").Range("I34")

Worksheets("MasterList").Range(issuedlocation).Value = Worksheets("Input").Range("D24").Value
'new entry balance update
Worksheets("MasterList").Range(balancelocation).Value = Worksheets("Input").Range("D27").Value

End Sub

I this code too taxing to cause slowdown?

Note: I am using Excel 2007

Can anyone help / guide?
