Match multiple criteria within range of values

Question

In Sheet1 I have several input values x , y and z in columns A , B and C . To simplify let's say I only have two rows with values (as in the picture).

In Sheet2 I have the thresholds; min and max-values for x , y and z , in addition to the corresponding codes.

I want to retrieve, in Sheet1 , all codes where the input values fall within the thresholds (matching the values) in Sheet2 . The codes do not need to be listed in the same cell if this complicates things; they can be listed in separate columns. I am also open for both formulas and VBA.

I know how to list several results using JOINTEXT if the criteria are exact matches. I also know how to list one result based on several inaccurate matches using INDEX + MATCH + <= >=. I don't know how to combine them.

I looked at these:

EXCEL index match by multiple criteria AND multiple match types?

...and tried this:

=INDEX(F5:L8;SMALL(IF(COUNTIF(F5:F8;"<="&A5)*COUNTIF(G5:G8;">"&A5)*COUNTIF(H5:H8;"<="&B5)*COUNTIF(I5:I8;">"&B5)*COUNTIF(J5:J8;"<="&C5)*COUNTIF(K5:K8;">"&C5);ROW(F5:L8)-MIN(ROW(F5:L8))+1);COLUMN(F4));ROW(F4)+6)

...without any result.

Answer 1

I managed to solve it by using Jeeped's impressive code (see comments). However, since I'm using comma (,) as decimals-seperator I needed to include a small adjustmen. I changed "iOptions", "iIgnoreHeaderRows", "i" and "j" from Variant to Double, and "a" from Variant to Long. I also included the following code:

Dim counter As Integer, sizeOfPairs As Integer
Dim test As String
counter = 0
sizeOfPairs = UBound(pairs, 1)

For counter = 0 To sizeOfPairs
    If TypeName(pairs(counter)) = "String" Then
        pairs(counter) = Replace(pairs(counter), ",", ".")
    End If
Next counter
