CAN SOMEONE GIVE ME A HAND ON HOW TO ADD A THRESHOLD LIMIT TO THE CATOEGORIES SECTION

Question

I WANT TO ADD A THRESHOLD LIMIT TO EACH CATEGORY IN THIS CODE.
LIKE FOR FOOD IT IS LET'S SAY 2500.
FOR BIKE : 1000
FOR GROCERIES : 3500
AND SO ON.

IF MONEY IS SPENT FOR FOOD BEYOND 2500, IT WILL BE COUNTED AS ' EXCESS MONEY SPENT',
EXAMPLE) IF MY SPENDING ON FOOD IS 3000, THE EXCESS MONEY SPENT ON FOOD WILL BE 3000-2500 = 500

IF MY SPENDING ON BIKE IS 3000, IT WILL DISPLAY : EXCESS MONEY SPENT = 3000-100 = 2000
SIMILARLY FOR OTHER CATEGORIES.

AT THE END , THE EXCESS MONEY SPENT ON EACH CATEGORY WILL BE ADDED AND THE USER WILL BE NOTIFIED ABOUT HIS OBERALL EXCESSIVE SPENDINGS

HERE IS MY CODE, CAN SOMEONE PLEASE GIVE ME A HAND ON HOW TO DO THIS.

Answer 1

Add one more field and track/display expence per each category also.

So user will see both per category if he select from dropdown menu and total expence.

Like in menu i select to see only for "bike", than i see list of my expences for this category,in expences is see my expances for bike but also total, you can set this div to display:none and only display whan user need it.

I think this is what you asking for.
