I don't really know how you set it up. Can you take a picture of the 1st screen and post it here? If you are doing what i told you and on the 1st GUI it says "food, amount" then yes it should.
If you're withdrawing 28 food, go to the bank tab and click "food" with 28, shouldn't make a difference.
in the uber_utils section, there is an option called banking. it allows you to take out certain things when going to the bank. i always make it withdraw my food for me.
when u start up the program a menu will pop up.
in the window, click on the box of options farthest to the left.
click on bank
click how many of the food u want to withdraw.
then find the actual food uw ant to withdraw in the menu
click the food.
now start the script
