point attribut doesn't work

[KillianDS]

Hello I have a problem attribut point which makes me an error

Error 
Unable to evaluate expression (Invalid number of arguments for function (/obj/LOD_Tool/rop_fbx3/sopoutput)). 
Error 
FbxExporter::Initialize() failed. Error returned: File not created

Here is what I put in my outputFile:

`chs("../File_export_LOD")``point(0,"Mesh_Name_9",0)`_LOD_`detail("../foreach_begin1_metadata1/","iteration",0)+1`

All works correctly except
`point(0, "Mesh_Name_9",0)`
t puts me in error, whereas when I put a attribwrangle2 with ca as code: 
string debug = point(0, "Mesh_Name_9",0);
printf("Check value : %f\n", debug);

It's a good way to return a string 
Check value : teapot

So it gets the right value but I don't understand why when I add it in my expression that works 
`chs("../File_export_LOD")`_LOD_`detail("../foreach_begin1_metadata1/","iteration",0)+1`
So that gives me this:
`chs("../File_export_LOD")``point(0,"Mesh_Name_9",0)`_LOD_`detail("../foreach_begin1_metadata1/","iteration",0)+1`
And now it doesn't work anymore how I can fix it I don't really understand what I'm doing wrong.

when using string values in HScript expressions, make sure you are using the string version of the channel calls: points(), prims(), details() etc. the "s" matters in these cases.
