DMax Problem

[DS]

I have a DMax problem. I need to get the highest Number in a series
froma table.
The table has this info...
1
1a
1b
2
3
3a
3b
3c
3d

Here is the DMax Statement
Me.TxtNumber = DMax("[Number]", "tblTest", "Len(Number)-1 = " &
Me.TextStart)

Me.TextStart would have a number such as 1, 2 or 3 in it.

So if Me.TextStart has the number 3 in it Me.TxtNumber would return 3d
if Me.TextStart had 1, it would return 1b, if it had 2 then it ould
return 2....you get the picture. Any help appreciated.
Thanks

Try;
Me.TxtNumber = DMax("[Number]", "tblTest", "Left(Number,(Len(Number)-1) = "
& Me.TextStart & "")

You were asking for the max number where me.TextStart = 1 (from you sample)

This works as long as there are only records as such...1a 1b
The minute you have mixed data such as 1 , 1a , 2 ,etc..it doesn't work...

Me.TxtNumber = DMax("[Number]", "tblTest", "Left(Number, Len(Number) -
1) = " & Me.Text3)

Ok I have this.
Me.TxtNumber = DMax("[Number]", "tblTest", "Left(Number,1)= " & Me.Text3)
The only hitch is that it works only up to 9 or single digit numbers,
double digits and larger are a no go.

Sorry not thinking straight there, try;
Me.TxtNumber = DMax("[Number]", "tblTest", "Left(Number,Len(" & me.Text3 &
") -1 ) = " & Me.Text3)

will find the highest 2 digit number if you enter 2 digits, 3 digit number
if you enter 3 etc etc.

scrub that last one do this instead!!!!
Me.txtNumber = DMax("[Number]", "tblTest", "Left(Number,Len(" & Me.Text3 &
")) = " & Me.Text3)

I left the -1 in by mistake!!!

will find the highest 2 digit number if you enter 2 digits, 3 digit number
if you enter 3 etc etc.

Ok Tony, It works until I go to double digits. Its says Data Mismatch?
This is what I have...
Me.TxtNumber = DMax("[Number]", "tblTest", "Left(Number,Len(" & Me.Text3
& ")) = " & Me.Text3)

Thanks for your help, it is appreciated!

OK Tony almost there. This almost works...

Me.TxtLast = DMax("[NumberID]", "tblTest", "Left(NumberID,Len(" &
Me.TxtCurrent & ")) = '" & Me.TxtCurrent & "'")

The only problem is if I have lets say a 4 and a 43 in the recordset
and Me.TxtCurrent is a 4 then instead of returning the highest record
for the 4 it will return the value for the 43 and not the 4.

I just did some experimenting...
It only happens if 4 has no other records. If I add a 4a record then it
doesn't happen.
