I need to create a function in column D that looks at column C.  If C contains an integer, move to the next.  When it encounters "--", write the value found in column A in column D, but I dont wan't it to skip lines.  Is this possible?  When working, it would look like this:

A     B     C     D
1     6     1     3
2     4     2     5
3     9     --    7
4     7     4
5     8     --
6     1     6
7     5     --

Lets' make sure we understand the example:

From the words I think that A3 being "3" should yield "3" in column D... but it doesn't.
Also rows A1 and A2 don't seem to have the right values in column D.

From the words it seems you'd expect this:
A     B     C     D
1     6     1     3
2     4     2     5
3     9     --    3
4     7     4
5     8     --
6     1     6
7     5     --

but from here I'm unsure because I don't know what you mean by "don't want to skip lines"  Which lines?  Input or output.  etc.

A simple way is to add a filter.
After that, in the column C filter, select just the "-"
then copy column A
remove the filter in column C
then paste the data into column D

You could use this formula in D1

=IF(ROWS(D$1:D1)>COUNTIF(C$1:C$100,"--"),"",INDEX(A$1:A$100,SMALL(IF(C$1:C$100="--",ROW(A$1:A$100)-ROW(A$1)+1),ROWS(D$1:D1))))

confirmed with CTRL+SHIFT+ENTER and copied down....it shows blanks when --s are exhausted, see attached

Here is an array formula approach, enter with Ctrl+Shift+Enter:

=IF(ROWS(D$1:D1)<=COUNTIF($C$1:$C$7,"-"),INDEX($A$1:$A$7,SMALL(IF($C$1:$C$7="-",ROW($A$1:$A$7)-ROW($A$1)+1),ROWS(D$1:D1)),1),"")

vb code would be fine

by not skipping lines, i mean this.  A vlookup could yeild this:

A     B     C     D
1     6     1    
2     4     2    
3     9     --    3
4     7     4
5     8     --    5
6     1     6
7     5     --    7

The extra step im looking for is to pull the values in column D up without blank rows between.  RSP eluded to using a filter.  Are the same results achievable with a function or vb code?

You could use an array formula in column D something like this:

=IFERROR(SMALL(IF(C1:C25<>"--","",A1:A25),ROW()-1),"")

ctrl+shift+enter to commit. The disadvantage is that you need to decide up front how many rows of original data you will not exceed. (In this case, 25 rows)

Good luck!

darren, you could take the steps I gave and make a vba procedure for that.
you could also make a function but it appears that barry and stephen gave you one that should work without VBA :)

Apparently the last example was something you *don't* want?
Please clarify by answering my original question.  Then maybe you will get better help.
An example would help.

In your first example there's a "7" in col D.  In my example there was a "3".  So, there's clearly a typo or a misunderstanding.

darrennelson: Would you still like a VBA code since you have got a formula to do what you want I guess?

rspahitz: it might look impressive, but that exhausts my repertoire of array formulae.

The formula is probably a good way to go.  However,if you want to replicate my filtering with a procedure, this might do it:
Sub AddDashValues()
    Range("C1").Select
    Selection.AutoFilter
    ActiveSheet.Range("$A$1:$D$8").AutoFilter Field:=3, Criteria1:="-"
    Range("A2:A999").Select
    Selection.Copy
    Range("D2").Select
    ActiveSheet.Paste
    Application.CutCopyMode = False
    ActiveSheet.Range("$A$1:$D$8").AutoFilter Field:=3
End Sub
