Problem using iLogic and iFeature.ChangeRow

[Binary12]

Hi,

I have a lot of similar punch tools I am trying to combine into one tool to be used in an iLogic driven assembly. 

I've been searching the forum for ways to change the punch tool and  found the following thread on how to change a table driven ifeature:

http://forums.autodesk.com/t5/inventor-general-discussion/ilogic-to-change-a-table-driven-ifeature/t...

This is a basic example of what I'm trying to do.

If ChangeType = "01" Then
iFeature.ChangeRow("Punch1", 01)

ElseIf ChangeType = "02" Then
iFeature.ChangeRow("Punch1", 02)


End If

However, despite trying a lot of different ways I cannot get it to work. I keep getting an error message eventhough I have created a custom column in the iFeature and named it as key.

Attached is the error message as well as the part, punch tool/ifeature that I've been using.

Would really appreaciate if someone could tell me what I'm doing wrong.

Best,

Fredrik

No one?

Feel like there must be something I did wrong when creating the punch tool as I've seen other use the same code and it works

I also tried following the example given in the Inventor 2016 Help section but get the same error.

(http://help.autodesk.com/view/INVNTOR/2016/ENU/?guid=GUID-020555BE-6197-4D27-8B31-A4D62E2CC2E8)

If size = "small" Then
iFeature.ChangeRow("RectangularPocket1", "Pocket-01")
ElseIf size = "medium" Then
iFeature.ChangeRow("RectangularPocket1", "Pocket-02")
ElseIf size = "large" Then
iFeature.ChangeRow("RectangularPocket1", "Pocket-03")
ElseIf size = "very large" Then
iFeature.ChangeRow("RectangularPocket1", "Pocket-04")
End If

Could this be a bug?

Big thank you to MjDeck for telling me where I went wrong!

Apparently table-driven ifeatures are not supported when inserted as a punch tool. When I insert the Punch tool or iFeature as a regular iFeature it worked like a charm! 

My intention for this is to combine a lot of similar hole patterns into one ifeature and to "hide" unneeded holes in the same spot as the active ones. For the creation of the product in mind this will save a lot of programming and features in Inventor which will in turn greatly speed up the process of keeping the ilogic model updated with any future changes.
