Steps

1. Open your tool script

Open the script inside your block tool.

2. Add an 'amount' variable

At the beginning of your code, create a new local variable called 'amount' and set it equal to Tool.Amount.
local amount = Tool.Amount

3. Make a new line at the end of your 'makeBlock' function

Find the last line of your 'makeBlock' functions and add a new line after it.

4. Subtract 1 from 'Amount' when a block is placed

At the end of you 'makeBlock' function, make a new line the sets 'amount.Value' equal to 'amount.Value - 1'.
amount.Value = amount.Value - 1

5. Make a new line after the line that checks the player's distance in 'onClick'

Go into the 'onClick' function and find the line that checks if 'distance' is less than 'PlaceDistance'. Make a new line after it.

6. Check if 'amount.Value' is less than 1

Use and 'if-then' statement to check if 'amount.Value' is less than 1.

Don't forget to hit the 'return/enter' key to get an 'end' statement.
if amount.Value < 1 then end

7. Return if amount is less than 1

Use the word 'return' to exit the function if the player does not have any blocks left.
return
