I am trying to script adding a vertical gradient blend for each brand name
section in a InDesign table.

The table can run as long as 40 pages and there can be from two to ten brand names per page. The gradient colors alternate between two colors for each brand.

I have a script which will work on the first page but the cells see their
offset from the beginning of the chart not the page they are on. The gradient on the other hand needs its starting point set to the page it is on. So starting on the second page I get what appears to be a solid fill which is really the very bottom of the gradient.

Here is the script.

tell application "InDesign 2.0.2"
	tell active document
		set theFrame to object reference of selection
		set theStory to parent story of theFrame
		set theTable to table 1 of theStory
		set rowCount to count of rows of theTable
		set brandRows to {}
		repeat with i from 1 to rowCount
			set rowColor to name of fill color of row i of theTable
			if rowColor = "SV Black" then
				set brandRows to (brandRows & i)
			end if
		end repeat
		set theGrad to "SV Gradient 1"
		set brandRows to (brandRows & (rowCount + 1))
		set brandCount to count of items of brandRows
		repeat with i from 1 to (brandCount - 1)
			set rangeStart to ((item i of brandRows) + 1)
			set rangeEnd to ((item (i + 1) of brandRows) - 1)
			set theStarts to height of rows 1 thru rangeStart of theTable
			set fillStart to 0
			set fillLength to 0
			set startsCount to count of items in theStarts
			repeat with i from 1 to startsCount
				set fillStart to (fillStart + (item i of theStarts))
			end repeat
			set theHeights to height of rows rangeStart thru rangeEnd of theTable
			set heightsCount to count of items in theHeights
			repeat with i from 1 to heightsCount
				set fillLength to (fillLength + (item i of theHeights))
			end repeat
			set fillLength to (fillLength * 12)
			set fill color of rows rangeStart thru rangeEnd of theTable to swatch theGrad
			set properties of rows rangeStart thru rangeEnd of theTable to {gradient fill start:{18, fillStart}, gradient fill angle:-90, gradient fill length:fillLength}
			if theGrad = "SV Gradient 1" then
				set theGrad to "SV Gradient 2"
			else
				set theGrad to "SV Gradient 1"
			end if
		end repeat
	end tell
end tell

Am I using the wrong approach or can I add a page identifier somehow?
