Macro to hide and unhide based on the condition in Checkbox and also Textbox

Hi Guys,

The macro code provided by chatgpt is working but then it only work partially.

anyone know how to correct the code?

In short i want excel to help me unhide column and only show me those that match my tickbox or month that input to the textbox here.

it is working halfway now, only tick will work, but when i input month for example 2, all the 2 together with the checkbox ticked will show. what i want is, when i tick actual and input 2, only actual with month 2 to show.

i have already spent the few hour with chatcpt to amend this but seems like it did not get what i want after so many attempt....
