Delete SOP not reading expression

[Sepu]

I cant get this to work for some reason ... I have this in a wrangle

 i@input = floor(rand(@ptnum) * atoi(chs("../get_geo/numobj")));

which is reading the obj merge, number of objects as you can see I also enable create primtive groups ..... the atrb i@input is giving me the correct output, random numbers from 0 to 2.

 

then I have a delete SOP which im trying to get a random delete of the objects upstream with this expression

input_`floor(rand(@ptnum) * ch("../get_geo/numobj"))`

 

I've tried this as well, but with not success

input_`point(../"number_of_inputs/", 0, "input",0)`

now if I use the Copy Stamp workflow it works

input_`stamp("../copy1/", "input", 0)`

 

anyone has any ideas or something that I can try that I might be missing?

just assign attribute for each object and make random for this attribute to delete.

or enable per-primitive path and use random_shash function in prim wrangle to make random on the string name.
