I want to populate asset in a assigned variable

[sri5]

My requirement is: X (reference) field calling below scriptinclude via advance reference qualifier. it will fetch the hardware assets related to current logged in users assignment group. we use this X field in multiple catalog items.and I have created system property, kept two sysids of catalog items in it. I need to populate the asset in X field onload for these two catalog items :- we have conditions that asset status is Instock ,substate is Available , asset function is New, Depreciation date should be old.
systemproperty has two sysids(items sysid)
for 1st sysid(item):we have "primary" variable's(reference to hardware) available in request item {1st sysid(item)}; we need to match "primary" variable manufacture and model.type(refers to model)
for 2nd sysid(item): we have pc , class variables which is select box type; pc has choices which is showing hardware assets->configuration item->operating system,; class variable which shows type of model.

for the rest of items it should follow the condition as status instock and substate as available.
