AutoIncrement Number

[burrina]

I have a Primary Key that I need to append to by using a increment counter of sorts. Example; EventID is 30 I then want to append to the same table that has this EventID but add a record with .1 to it so that the new EventID would be 30.1 and the next would be 30.2 and so on.
[EventID]+.1 And [Forms]![frmmissedevents]![EventID] I have this is a query grid to try and accomplish this, will this work?
I will have several records in the table I am appending from with the SAME EventID
I am using a form and append qry to try and accomplish this. I have a table with missed events that did not take place and need to add them back in but keep all of the original data except to update the dates, check number and some yes/no fields.



For each missed event in my table I run the append query to modify the table tblEvent
Example: Also needed is: Let's say my PK is 30 (EventID) and I want to change the below
tblEventID EventID is PK
MyDte Check Date
EventStart Date() also used as check date
ChkNo Greatest Check Number

Let's say also that for ALL other EventID that are 30 I just need to increment the EvenID by .1 so it will be 30.1 and advance from there.

I don't fully understand your post. I see EventID values repeating in your attachment - so clearly it is not the primary key field (which I guess is not displaying - which is fine). If the EventID field type is integer - then it must be changed to Single or Double to permit decimals - but then you should be able to add records to this table with 30.1

Manually typing in 30.1 is fine of course. Automating that however is not easily set up. I see 4 records with EventID 30 - automating to change those to be 30.1, 30.2, 30.3, 30.4 would be tricky. First of all for the db to know which should be which (if it matters)...but I'm not sure from your post as to whether this is what you seek.

Why is this necessary on form? Textbox on report has a RunningSum property that can be used to sequentially number records in each group.

If you must save that value to table there are various methods.
