Solution Part the 1st:

As Mike has said: build a milti-value key using GetNthRecord()

OR

create a self-join Cartesian relationship:

<layoutTO>::<anyField> x <newTO>::<anyField>

base your portal on the new TO and filter the portal with the formula:

<newTO>::danSeq > Get ( RecordNumber ) - 10
and
<newTO>::danSeq < Get ( RecordNumber ) + 10

(if you have, or will ever have, a vast number of records screen updating may prove to me unacceptably slow)


Solution Part the 2nd:

I'm assuming that you already have an invisible button in the portal; make sure it's behind everything else in the portal and Conditionally Format its fill colour with the formula:

<layoutTO::danSeq = <portalTO>::danSeq

If you haven't already got a button, you could use a text box containing a single space - or if you have a single field in the portal, you could Conditionally Format that.

[it appears that you are attempting to use a calculated field to provide the highlight rather than native Conditional Formatting]
