Register placement of block from item stack

[Omanoctoa]

I have a frustrating issue, I've searched high and low for an answer and can't figure it out, but I know it's something extremely simple.

I place a Cauldron, and it should add the Cauldron to a list. This works, but ONLY if I have a single Cauldron in my hand when I place it down. If I am holding more than one (ie a stack of 64; even just 2) it doesn't recognize I've placed it and add it to the list. I can click all I want (in survival or creative) and it just places Cauldrons until I get to the last Cauldron (because that means I'm only holding 1). I can use "an amount of" instead of "is 1 of", but then it only works if the player is holding multiple of the item. I need it to test for 1 or more without duplicating my code (there's a lot of code).

Snippet from my code:

on place of cauldron:
    if player's tool is 1 of cauldron named "&cBroken Cauldron":
    if player's tool an amount of cauldron named "&cBroken Cauldron": #ALTERNATIVELY, I have tried this...
        set {_loc} to location of event-block
        add {_loc} to {cauldrons::*}
        send "Cauldron placed!" to player

I have also tried - remove 1 of player's tool from player's tool - but this isn't really helpful.

I've found a similar thread on MineHut but no viable solution:

set {_amount} to item amount of held item of player


You can get item with: {_amount} of held item of player

Or

if held item of player is (item amount of held item of player) of held item of player:

2nd is more good. Try both of them and send if there are any errors. Not tested.

This seems like an over-complicated solution but seems to work, thanks.
