Missing function for lightbox layout

[VirtualBob]

I was looking for simple lightbox layout for images. I'm using FMP 15 and the only example I could find was from FM7. I got most of the script imported set up but it stalled on FoundSetValues("ImageData::ImageID") and says the function doesn't exist. It works if I open the original converted file but not if I import it into my current image database. Is there a quick replacement for this?

The script is below and link to the lightbox file further down.

Set Field [ Lightbox::gSetValues;
 FoundSetValues("ImageData::ImageID") ]

Set Variable [ $SetSize; Value:ValueCount(Lightbox::gSetValues) / 7 ]

Go to Layout [ “Lightbox” (Lightbox) ]

Show All Records

Loop
Exit Loop If [ Get(TotalRecordCount) ≥ $SetSize ] New Record/Request
End Loop

Go to Record/Request/Page [ First ]

FoundSetValues() is a custom function. If you have the Advanced version, you can copy/paste or import it into your file.

Yes, but ... are you really using version 12?

Apologies - I'm on version 15 (I used 12 for years and its wired into my brain :-)

I don't use custom functions, although I suspected it might be one but its not referenced elsewhere that I could see, but as it worked in the converted (v7>v15) file I thought it would import OK. But when I import it that functions string gets commented out and if I un-comment it it says "this function cannot be found". I could be missing some other background connection so I thought I'd post here.

If you don't have the Advanced version, then you cannot manage (create, edit, import) custom functions. You can only use custom functions installed by  someone else.

In your case you could define a summary field in the ImageData table as List of [ImageID]. Then make the script set the global field to this summary field.
