            Usually you would add money to this
            @if($piggybank->repeated == 1)
                repeated expense
            @else
                piggy bank
            @endif
            by transferring it from one of your accounts to "{{{$piggybank->account->name}}}". However,
            since there is still {{mf($maxAdd)}} on that account not locked in any piggy bank or repeated expense,
            you can also add it manually.

            @else

            If you need the money in this
            @if($piggybank->repeated == 1)
                repeated expense
            @else
                piggy bank
            @endif
            for something else, you can opt to remove it using this form. Since there is {{mf($maxRemove)}} in this
            @if($piggybank->repeated == 1)
                repeated expense
            @else
                piggy bank
            @endif
            that is the maximum amount of money you can remove using this form.
            @endif
