I have this code that I have put together and it works fine as long as none
of my numbers are "0's" or blank cells.

'Inserts A Header and formula
Range("AU2").Select
ActiveCell.FormulaR1C1 = "A"
Range("AU3").Select
ActiveCell.FormulaR1C1 = _
"=EXP(INDEX(LINEST(LN(RC[-25]:RC[-15]),R1C22:R1C32),1,2))"

'Inserts B Header and formula
Range("AV2").Select
ActiveCell.FormulaR1C1 = "B"
Range("AV3").Select
ActiveCell.FormulaR1C1 =
"=INDEX(LINEST(LN(RC[-26]:RC[-16]),R1C22:R1C32),1)"

In my spreadsheet I have values from $V$1:$AF$1 (always constant) which are
my X values, V3:AF3 are my Y values. The formula works great as long as
there are no 0's or blank cells, I have tried to work around this in terms of
HLOOKUP and VLOOKUP but it has become more troublesome than its worth.

Is there a way to code this so that if there is a blank value that it will
ignore the 0 or blank and the coresponding X value (from $V$1:$AF$1). The
reason the formula messes up when there is a 0 or blank cell is that you
cannot take the ln(0) or a blank cell.

Thank you for your help.
