@Metahofzicht Nailed it. I found out how to fix it.

My grading code:

local I:=II:
if evalb(simplify(algsubs(I = a^4/(32*sqrt(3)), algsubs(C = 192, $RESPONSE) = $RV1))) then 1.0;
elif evalb(simplify(algsubs(I = a^4/(32*sqrt(3)), algsubs(C[1] = 192, $RESPONSE) = $RV1))) then 1.0;
elif algsubs($fact2 = 1,$RESPONSE) <> $RESPONSE then 1.0;
else 0.0;
end if;

Custom previewing code: local I:=`I `:printf(MathML[ExportPresentation]($RESPONSE));

my algoritm:

$fact2 = "E*a^4/L^3";
$RV1 = "$fact2*2*sqrt(3)";
$RVdisplay = "printf(MathML[ExportPresentation]($RV1))";

Sure. But I changed the name now. Should I undo the changes?

Thank you, I just sent you the texts.

No problem @mathstutor. From my investigations I came to the same conclusion.

WIth regards to point 4, if you use a single line comment in the javascript box your question will be displayed in a small (300x150px) box

@swinkler I also see this behaviour. Can you email this to support@maplesoft.com. I might be useful to send a screencast video with the email. I am also happy to do this if you are busy.

Thanks for looking into this! Unfortunately we do not (yet) have a local server for MapleTA, but this security issue could be an argument for becoming self-hosted. One way around the concrete problem (without self-hosting, I think) is to embed the needed (if not all) *.mla procedures directly via manual copy-paste into the startup code from the worksheet that defines the *.mla file. But this, of course, is much more cumbersome than the wished-for simple one-line reference to the *.mla file itself.

Your answer, however, then also induces a similar question concerning the use of repository files inside MapleTA itself, as thoroughly explained in:
[https://mapletacommunity.com/topic/64/how-to-create-and-use-a-maple-repository-in-maple-ta].
Admittedly, I did not check this out yet, but the question is, if this functionality also has been depreciated or blocked in the meantime?

Thank you very much in advance!

Yes, I'm using the 2016 version. It worked, thank you! I used $x*$response.provachain1.1.1 in the response area, where $x=4; was defined as the only line of the algorithm. Good to know also that it is wrong to consider the (addable by the user) field "id" from "Information Fields" as equivalent to the "id" appearing in the source, which is not the case.

If you have a list of answers as a variable in the algorithm section of your question. e.g.

$TA=["2*Pi",5,"x/y"];

You can put the following grading code to award points based on how many input boxes have the correct answer.

TA:=$TA: RESP:=$RESPONSE: grade := 0.0: for i to nops(TA) do if TA[i] = parse(RESP[i]) then grade := grade+1.0/nops(TA); end if end do: grade;

The order of answer boxes in the html must be the same as the order in $TA. With this code each box is worth 1/n, where n is the number of answer boxes.

@jmtrik If .js files are not allowed, you can get around this by uploading them as .txt and linking to those.
