Script help!

[SLAMnesia]

I have quite the situation for anyone willing to help

I want to have this system for unlocking a door, heres my idea:

-the door is locked and the padlock has rusted

-First, you need to get the rust of the lock, and you go about doing that by getting a glass_container_1 and using that to pick up a poison_gland_1 (by pick up, i mean double clicking the glass_container_1 in your inventory and then clicking on the poison_gland_1) combining the 2 into an item glass_container_mix_done_1 (have it spawn in your inventory). Then using the glass_container_mix_done_1 to unrust the lock and remove the glass_container_mix_done_1 from inventory. THEN finally unlock the door with key_study_1 and zam ur in.

Please help, if you get some working script for me I will put you in my credits
