Well, I have taken it from tha DataReportExample, from the FABout form:

PUBLIC SUB timAuthor_Timer()
  DIM Y AS Integer
  Y = svwAuthor.ScrollY
  INC svwAuthor.ScrollY
  IF Y = svwAuthor.ScrollY THEN svwAuthor.ScrollY = 0
END

Yes, I do.

It is the same I believe, but neither INC  Scrollview1.ScrollY nor the istructions

Y=Scrollview1.ScrollY
INC Y
Scrollview1.ScrollY=Y

nor

Scrollview1.ScrollY=Scrollview1.ScrollY+1

work

Scrollview1.ScrollY is always set to zero.
