Excel2003

I am using the following code to add a record to my collection page.

Dim LP1C1ARNU As Double
....
....
Range("D" & LRow - 1).Value = LComments1 & " " & LRun & " " & "P1C1AR" & "="
& LP1C1AR & " " & "P1C1ARNU" & "=" & LP1C1ARNU

LP1C1ARNU is from another page in percent format, but shows up in the new
cell as a Decimal.(ex P1C1ARNU=.157)
How can I show it as Percentage?(ex P1C1ARNU=15.7%)

I would also like to know how to add "alt enter" to the expression so I can
line up the values in the cell.
