Access IIf statement help

Hi,

I'm having problem with the last part of my formula IIf([Column1]>[Column 2],[Column 2]))).    When I run the query, Column 1 is returning instead of Column 2, can you please assist?


IIf([Column 1]<"0","0",IIf([Column 1]<[Column 2],[Column1],IIf([Column1]>[Column 2],[Column 2])))

You might want to replace the nested IIF() statements with a Switch statement

Switch([Column 1] < "0", "", [Column 1] < [Column 2], [Column 1], True, [Column 2])

But what if either of those columns is NULL, you might want to try:

Switch(Val(NZ([Column 1], 0)) < 0, 0, NZ(Column 1], 0) < NZ([Column 2], 0), [Column 1], True, [Column 2])

In your formula, you don't have anything that takes care of the situation where Column1 = Column2.  Both Jim and Dale gave you solutions that corrects that.  

In case you aren't aware though, I do want to point out that it looks like you're comparing string values and not numeric types.  So that may be a possible reason on why you think it's not working correctly.

Take a look at this sample of how the 2 data types behave differently:
Column1     Column2     Column1<Column2
  "11"        "3"           TRUE
   11          3            FALSE
