How to Extract Data from Multiple IQ Bot tables based on Scenerios

Can someone please help me with this. In below image i have 2 tables in IQ Bot, where I need to match Item_Total of 1st table with Itemtax1 of second table and update Item_Tax_Rate of 1st table with itemtax2 of table2.

Ref Image 1 attached.

I tried executing the code shared by you but getting error as it says table2 not recognizable.

Can you review below and suggest.
