I'm just starting to play with Access after getting a basic grasp of VB in Excel.
I have a really basic problem which despite hours of surfing I can't find the answer to;

I have done a very basic table with 2 fields. Table called 2984 and field 1st field called ServiceNo.
The serviceno values stepping up incriments of 0.5

All i want to do is get the highest value in the column ServiceNo and add 2 to it ( the rest i'll be abe to work out). then put the new value back into the table as a new record. I've been round and round in circles with code so i must be missing something very basic in my understanding.
Any help would be great to get me started, thanks

I have been playing with the following code without any joy
Code:
Sub New_Day_Member_Table()
Dim Dty As Single
Dim Dte As String
DoCmd.SetWarnings False
[COLOR=red]Dte=DoCmd.RunSQL "SELECT MAX(ServiceNo)FROM 2984;"[/COLOR]  [COLOR=lime]' i want to assign Dte to the value of the highest value in ServiceNo[/COLOR]
    Dty = Dte + 2
    DoCmd.RunSQL "INSERT INTO 2984(ServiceNo, Duty) values(' " & Dty + 2 & " ', ""Day"");"
    DoCmd.RunSQL "INSERT INTO 2984(ServiceNo, Duty) values(' " & Dty + 0.5 & " ', ""Night"");"
End Sub
 

Excel Facts

Waterfall charts in Excel?
Office 365 customers have access to Waterfall charts since late 2016. They were added to Excel 2019.
sorry, whilst trying many variations i've changed my original,
Dim Dte As String should be Dim Dte as Single
