Variable Help?

[QmanRocks]

I'm trying to code a feature where when you click a sign with certain text on it, you will purchase a rank (if you have enough money).

on rightclick on sign:
    if line 2 is "Plus Rank":
        set {_balance} to value of placeholder "vault_eco_balance_fixed" from player
        set {%player%.rank} to value of placeholder "vault_rank" from player
        if {%player%.rank} is "default":
            if {_balance} is greater than 174:
                make console execute command "/lp user %{playername}% parent set plus"
                send "Successfully purchased Plus Rank!"
                make console execute command "/eco take %player% 175"
            else:
                if {_balance} is less than 175:
                    send "&cYou don't have enough Gems!" to player
                else:
                    send "%{_balance}%" to player <
        else:
            send "&cYou already have a better rank! All of the stuff from the previous ranks pass over." to player

I'm using a plugin to import Placeholders from PlaceholderAPI, and if I test out the placeholder for balance, it registers as $350. But, the code doesn't give me the rank. It instead goes to where the < symbol is. I don't know why the code isn't working, but I feel like it isn't recognizing {_balance} as an integer. Any help would be amazing!

use player's balance expression, you can add or subtract from it
