Inventory and distribution sheet

hi all. So this may not even be possible (which I don't entirely believe), but I have one sheet which is tracking our entire inventory in rows A and B. On the second sheet is a log which tracks all of our distribution column A is the Item item name and column D is the quantity issued.

My question is this: Is there a way I can have the inventory on sheet 1 identify the item selected from the drop down in Column A sheet 2, and the quantity selected in column D sheet two and auto update the inventory number in column B sheet 1.

Ive been fighting with this for days and the finished product is needed ASAP so any and all help would be greatly appreciated.

Thank in advance!!

Here's a basic replica with all the actual (sensitive) data removed, Hope this helps in finding a solution.

I think I figured it out! I used the formula =SUMIF(Table1[Item],Table2[[#This Row],[Item]],Table1[Quantity Issued]) to determine how many of each item were issued and placed said formula in a new range (chart). Then using the formula =SUM(Table2[[#This Row],[Initial count]],-Table2[[#This Row],[Currently Issued]]) in the Quantity in stock column the list auto-populates any inputs from the Issue log. If you folks have a better way of doing this I'm all ears but this is definitely doing what I was hoping it would.
