filtering items depending on "object number"

Hi,

I try to filter all items depending on the attribute "object number" which should be something like 1.2 or 1.3.0-2 ...
I have no problems using filter on other attribute names and if I insert the attribute "object number" by hand there are no errors and I can see them in the column. But If I implement it in the script I get an error like "unknown attribute".
Does anyone has an idea how to get that right?

My aim is to filter the items e.g. between 1.2 and 1.6

thank you for your help!

Henrik

actual code:

const string filtermodes[] = {"Absolute Number", "Object Type", "Absolute Number", "Test Status"}

int filter_button_choice = 0

...

input_filterword = get(filter_word_box)

...

input_filterword_1 = get(filter_word_box_1)

...

f  =  attribute filtermodes[filter_button_choice] >= input_filterword
f1 =  attribute filtermodes[filter_button_choice] <= input_filterword_1
f  =  f&&f1

filtering off
set f
filtering on
refresh current

Filter f = attribute("Object Number") >= "1.3.1" && attribute("Object Number") < "1.4"

set f;
filtering on;

works fine for me, or am I misunderstanding something?
