Set variable for a For Loop -

I need to loop thru a series of data fields and be able to change the number with in the field name.

is.  Q1T1, Q1T2, Q1T3,Q1T4, Q1T5, Q1T6,
      Q2T1, Q2T2, Q2T3.Q2T4, Q2T5, Q2T6,
      Q3T1, Q3T2, Q3T3,Q3T4, Q3T5, Q3T6,
      Q4T1, Q4T2, Q4T3,Q4T4, Q4T5, Q4T6,
      Q5T1, Q5T2, Q5T3.Q5T4, Q5T5, Q5T6,
      Q6T1, Q6T2, Q6T3,Q6T4, Q6T5, Q6T6,

Total of 36 fields that I will need to be able to capture the value so that I may compare it to another value to see which is greater.

So I want to simplify this by using a variable for the 2nd position and 4 position.  What is the best solution.


I will need to be able to increment the numbers to compare the value of

Q1T1 > Q1T2

Hence the need to  Q1T & (i) + 1 = Q1T2, etc.

This is my first attempt.
                     While rs.EOF = False
                       For nQtr = 1 To 6
                            For ntr = 1 To 6
                            i = "Q" & nCt & "T" & ntr
                            n = 1 + 1
                           If rs.Fields("Q" & CStr(i)).Value = True Then
                           
                           
                           End If
                       Next
                       rs.MoveNext
                    Wend

To refer to the fields you can use rs.Fields("Q" & nQtr & "T" & ntr), so the code would look something like this.
While rs.EOF = False
    For nQtr = 1 To 5
        For ntr = 1 To 5

            strField = "Q" & nQtr & "T" & ntr

            strNextField ="Q" & nQtr & "T" & ntr+1

            If rs.Fields(strField).Value > rs.Fields(strNextField).Value Then
                           
                           
            End If

        Next ntr
    Next nQtr

    rs.MoveNext
Wend

PS There is no need for CStr.

Could be:

While rs.EOF = False
    For nQtr = 1 To 6
        For ntr = 1 To 6
            i = "Q" & nQtr & "T" & ntr
            If rs.Fields("Q" & CStr(i)).Value = True Then
                ' Do stuff.
            End If
            ntr = ntr + 1
        Next
        nQtr = nQtr + 1
     Next
     rs.MoveNext
Wend

Just debugging the logic in what you have there:
                       For nQtr = 1 To 6
                            For ntr = 1 To 6
                            i = "Q" & nCt & "T" & ntr
                            n = 1 + 1
                           If rs.Fields("Q" & CStr(i)).Value = True Then

Open in new window


should likely be
                       For nQtr = 1 To 6
                            For ntr = 1 To 6
                            i = "Q" & nQtr & "T" & ntr
                           If rs.Fields(CStr(i)).Value = True Then

Open in new window


And then you can just reuse nQtr and ntr in the body of the If block itself adding whatever number is appropriate to get to the field to compare to (can't give much more detail than that, just depends on how you're trying to compare all the fields).

ok all are great examples, Thanks, however, once the ntr value = 6 then I do not want to be able to increment to 7.

What do I need to do to the "strNextField ="Q" & nQtr & "T" & ntr+1' to prevent the incrementation?

If you notice in the code I posted the loop only goes to 5.

with a properly normalized schema, you would do this with a query.

Select Max(yourField) From your table
Where SomeDate Between Forms!yourform!StartDate AND Forms!yourform!EndDate;

You should add an Option Explicit statement in your General Declarations section.  The compiler would have caught the variable name spelling error.

Thanks these are the changes I needed thanks for your input.  Note; to the statement about the Option Explicit.  I just didn't include it in the value I posted, but always use it.  Thanks. for the comment.

When you're tired of writing code to deal with the unnormalized table, let us know and we will help to normalize it.

Unfortunately, I am working a project, where that is just not the case, and i am wrapping the project up.  I inherited the project, and It is a real mess.  but hire only to fix a couple of reports, not the entire database.  Thanks for your input.

I ended up creating a Union query to semi normalize the data, hoping this will make comparison a lot easier.
