Hm, I can't reproduce what you write.<br>
Could it be that you checked on macOS? Maybe it's different there?<br>
<br>
Here is a screen cam video that shows what I wrote:<br>

when Finale 27/Win10 is (re-)started the first plug-in call returns
the correct <i>errmsg </i>(here: "false" which comes from clicking
"Cancel" in the Perfect Layout user dialog).<br>
The second time I run Perfect Layout with the same clicks, <i>errmsg
</i>is <i>"".<br>
</i>If I restarted Finale once more (which is not in the video), it
would again show the correct <i>errmsg </i>the first time, but an
empty value on subsequent calls.<i><br>

<div>Okay, so it isn't exactly a bug. ExecuteLuaScriptItem
returns the top value on the Lua stack, which is the *last*
value returned. So the question is, do I modify it to return
the first value returned (i.e., the last value on the stack),
or do I modify the docs to say it returns the last value
returned?</div>

<div> Robert,<br>
<br>
thanks a lot for v0.66!<br>
<br>
I have been testing the compatibility with Perfect
Layout and also tried the new "return value" handling.<br>
It seems to me like there is still a problem. I tried it
in Fin27/Win10/RGP Lua v.66.<br>
<br>
I call the plug-in with:<br>
local success,d1,d2=finenv.ExecuteLuaScriptItem(script)
<br>
<br>
When the plug-in ended without error, but with:<br>
return 11,12,13<br>
<br>
The script above gave these values:<br>
success=true<br>
d1=13<br>
d2=0<br>
<br>
I think this is correct. (However, I have not found it
in the documentation.)<br>
<b><br>
</b><b>BUT: </b>this only happened the very first time
when I called the script directly after starting Finale.<br>
When I run the ExecuteLuaScriptItem a second time, it
always results in:<br>
<br>
success=true<br>
d1="" --or at least it's an "empty nothing"
when I print it with tostring(d1). It's not nil.<br>
d2=0<br>
<br>
So after the first run I can't influence the return
value anymore.<br>
Seems like the return value is permanently stored
somewhere in RGP Lua.<br>
<br>
When I restart Finale, it's the same behaviour: first
time correct value 13, after that "".<br>
