IF statements for table array

Hi,

I want to use a simple if statement to return a value in a table array.

For Example
Rate = 0.2
A1: 100
A2: 150
A3: 200
A4: Future data entry
A5: Future data entry

Where I require the calculation to take the most recent value "A3" and subtract from the its predesessor "A2", then multiply by the rate (0.2).

Where I am getting stuck is when future data is entered i.e. "A4" (Making "A5" future data entry) and therefore must subtract from "A3", and multiply by rate (0.2)

Hope this makes sense

Thanks

doubt this is the best way to do this, but:
<TABLE style="WIDTH: 96pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=128 border=0><COLGROUP><COL style="WIDTH: 48pt" span=2 width=64><TBODY><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext 0.5pt solid; BORDER-LEFT: windowtext 0.5pt solid; WIDTH: 48pt; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" align=right width=64 height=20>100</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext 0.5pt solid; BORDER-LEFT: windowtext; WIDTH: 48pt; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent" align=right width=64>0.2</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" align=right height=20>150</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent" align=right>10</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" align=right height=20>200</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent"> </TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext 0.5pt solid; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" align=right height=20>250</TD><TD class=xl63 style="BORDER-RIGHT: windowtext 0.5pt solid; BORDER-TOP: windowtext; BORDER-LEFT: windowtext; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent"> </TD></TR></TBODY></TABLE>
Cell B1 is Rate
Cell B2 Formula:
=B1*(INDEX(A1:A1000,LARGE(ROW(A1:A1000)*(A1:A1000<>""),1),0)-INDEX(A1:A1000,LARGE(ROW(A1:A1000)*(A1:A1000<>""),2),0))
Ctrl+Shift+Enter

Hello,

If you don't have blank cells before the last value, try this

=(LOOKUP(1E+307,A:A)-INDEX(A:A,MATCH(1E+307,A:A)-1))*0.2

=B2 * (INDEX(A:A, MATCH(9E+307,A:A,1)) - INDEX(A:A, MATCH(9E+307,A:A,1)-1))

The Blue returns the last number in column A
The Red returns the 2nd to last number in column A
There has to be a least two numbers in column A

Thanks all,

I ended up using a Lookup which worked perfectly

Cheers,
