Hello, I have an editable grid that allows for columns to be added dy

...LastName,
saveInto: ri!items[ri!index].LastName << fn!trim
),
a!dropdownField(
label: "Country" & ri!index,
required: true,
choiceLabels: ri!activeCountries.CountryName,
choiceValues: ri!activeCountries.CountryID,
placeholderLabel: cons!FRMR_DROPDOWN_SELECT_ONE_TEXT,
requiredMessage: "A Country is required for this field.",
value: ri!items[ri!index].CountryId,
saveInto: ri!items[ri!index].CountryId
),
a!textField(
label: "Province" & ri!index,
value: ri!items[ri!index].Province,
saveInto: ri!items[ri!index].Province << fn!trim
),
a!linkField(
label: "delete " & ri!index,
align: "CENTER",
links: a!dynamicLink(
label: "Delete",
value: ri!index,
saveInto: {
a!save(
ri!items,
remove(
ri!items,
save!value
...

... )
),
a!save(
ri!itemsToken,
remove(
ri!itemsToken,
save!value
)
)
}
)
)
}
)
)

Can you attach the grid code?

Certainly. This is the Grid code and the Row code.

Grid Code.txt

Row Code.txt

how is your local!itemsToken defined? In the past how this tokens variable is defined has caused issues with deleting the last item in an editable grid for me.

It is simply loaded as a local variable on the form.

How should I define the variable to avoid this issue?

see if "local!itemsToken: {}" helps

I tried that to no avail.

I was looking at my code when I gave that suggestion! Assuming you itemsToken definition is in a load() try defining "local!itemsToken: ri!externalPerson" The out of bounds array issue is because your rule input has data in it but your token has not yet been initialized so in the gridRow code when you try to remove a value, you can successfully remove it from "ri!items" since it already exists, but we haven't put it in "ri!itemsToken" so we can't remove what isn't there.
