Multi layered sub ID's

I created an Excel spreadsheet with a multi-layer id system like this
IdLayers.PNG

I have ID and DataID setup to generate there ID's the way i want I'm just having a little trouble with the subDataID.
when creating a new form i want to check if DataID value has ever been created before and if so to create a new subDataID value 1 for that DataId value and Increimate subDataID =+1 for every time a new DataID with the same DataID is created.

Maby something like this.

 

 

if(DataIDCard.Text <> LookUp(Table,DataID),Set(subDataIdVariable,1),Set(subDataIdVariable,Max(Filter(Table2,DataID = "10"),subDataID)+1))

Hi @natmaxex ,

Do you want to check whether there's subDataID, if yes last subDataID+1, if no start from 1?

If so, the key point is to use LookUp function to get whether there's existing DataID.

You should use formula like this to get field value:

LookUp(table,condition,fieldname)

The formula that you used: LookUp(Table,DataID) will only get a record. You use use IsEmpty to justify whether that's record, not to compare a value with a record.

 

Try this formula:

If(
    IsEmpty(LookUp(Table2,DataID=DataIDCard.Text)),
    Set(subDataIdVariable,1),
    Set(subDataIdVariable,Max(Filter(Table2,DataID = DataIDCard.Text),subDataID)+1)
  )

Thanks, I find this works a lot better.

If(
    IsBlank(LookUp(PeoplePurchasDev,DataID=DataCardValue6.Text,DataID)),
    1,
    Max(Filter(PeoplePurchasDev,DataID=DataCardValue6.Text),subDataID)+1
)
