Hi
In my scene I have a null node called "Precise_Clipping "where I edited the parameter interface and added a toggle called "precise_clip" then In the voxel size channel of a vdb node I have written the following:
if (ch("../Precise_Clipping/precise_clip") == 1)
{
return 0.01;
}
else
{
return 0.2;
}
The problem here is that it gives this error:

Its not the first time I write expression in channel fields, and to me the syntax looks correct...so whats the error?
Thanks
