--- Comment #9 from Eike Rathke <er...@redhat.com> --- Normally (...) for user defined functions that are invoked as spreadsheet functions, yes. Now it gets complicated: for whatever reason (I don't know the history behind that specific VBA implementation) if there is Option VBASupport 1 which here is the case then a XCellRange object is passed for cell references. That indeed allows BASIC to modify the cell. It should not and can result in undesired side effects, like here even Err:522 circular references being detected because the cell value modified triggers another recalc that runs into a currently being calculated cell. Changing stableford() to not modify its score argument gets rid of all side effects. -- You are receiving this mail because: You are the assignee for the bug.
