ISERROR Functin to Much Work!

I often use the ISERROR function to wrap around a formual that may hav
a an error in it. I use if nested in an If stmt to say if the formua
generates an error, then produce a zero value otherwise, do I want
want it to. For example:

IF(ISERROR(A1/B1),0,A1/B1)

Problem is that you have to type in the fist part of the formual A1/B
again at the end of the IF stmt. This is really a pain if the conditio
is ver large:

=IF(ISERROR(IF(Inputs!$G$550
"Denominator",(Statements!H101+Statements!H102)/(Statements!H101+Statements!H102+Statements!H106),1)),0,IF(Inputs!$G$55

"Denominator",(Statements!H101+Statements!H102)/(Statements!H101+Statements!H102+Statements!H106),1))

Is there a formual or userdefined function that acts like an iserro
wrapped in an If stm that will allow me to not repeat the formula? I
would look like this:

Iserror2(condition,result if condition is false)
or
Iserror2(A1/B1,0)
or
Iserror2(IF(Inputs!$G$550
"Denominator",(Statements!H101+Statements!H102)/(Statements!H101+Statements!H102+Statements!H106),1)),0)

Does anybody know if this exists or hoe to build this in VBA?

Hi
this ISERROR2 kind of function does not exist directly in Excel. You
can of course create it.
for storing a variable have a look at
http://makeashorterlink.com/?J32E23767
(option 2+3 -> the latter one reposted below)

Public Function V(Optional vrnt As Variant) As Variant

Static vrntV As Variant
If Not IsMissing(vrnt) Then vrntV = vrnt
V = vrntV
End Function

Tom Ogilvy presented this UDF yesterday.......

Function Noerorvlookup(Lookup As Variant, Rng As Range, Col As Long)
Dim res as Variant
res = Application.VLookup(Lookup, Rng, Col, False)
If IsError(res) Then
Noerorvlookup = 0
Else
Noerorvlookup = res
End If
End Function

OR a macro to add the ISERROR to existing formulas.......

Sub ErrorTrapAdd()
Dim myStr As String
Dim cel As Range
For Each cel In Selection
If cel.HasFormula = True Then
If Not cel.Formula Like "=IF(ISERROR*" Then
myStr = Right(cel.Formula, Len(cel.Formula) - 1)
cel.Value = "=IF(ISERROR(" & myStr & "),""""," & myStr & ")"
End If
End If
Next
End Sub
