Saving to wrong table

[Humanity]

Natural Gas Bill Recorder (I'm not done coding the totals buttons because I'm having a Save Button issue....

I set the year... that works.

Can update every years month of January... that works.

BUT... Change the month & it saves all other months into Year #3???

I use these 3 buttons to set the year:

 YEAR BUTTON 2018 : ONSELECT

Set(GasYear,"3");

UpdateIf(NG1,GasMonth="January",

{Year:'Year Dropdown'.Selected.'Garage Walls Attached'});

UpdateIf('Natural Gas 2',GasMonth="January",

{Year: 'Year Dropdown'.Selected.'Garage Walls Attached'});

UpdateIf('Natural Gas 3',GasMonth="January",

{Year:'Year Dropdown'.Selected.'Garage Walls Attached'})

GALLERY : Items

If(GasYear="1",NG1,If(GasYear="2",'Natural Gas 2',If(GasYear="3",'Natural Gas 3')))

GALLERY - Snapshot

GALLERY - LABEL (Blue Months Above) : OnSelect

ThisItem.GasMonth

SAVE BUTTON : ONSELECT

If(
Gallery1.Selected.Year = "1",
UpdateIf(
NG1,
Gallery1.Selected.GasMonth = GasMonth,

{
Provider: 'NG Provider'.Text,
Cost_GJ: 'NG Cost'.Text,
Monthy_GJ: 'NG How Many'.Text,
Admin_Fee: 'NG Admin'.Text,
Delivery_Fee: 'NG Delivery'.Text
}
),
If(
Gallery1.Selected.Year = "2",
UpdateIf(
'Natural Gas 2',
Gallery1.Selected.GasMonth = GasMonth,
{
Provider: 'NG Provider'.Text,
Cost_GJ: 'NG Cost'.Text,
Monthy_GJ: 'NG How Many'.Text,
Admin_Fee: 'NG Admin'.Text,
Delivery_Fee: 'NG Delivery'.Text
}
),
(UpdateIf(
'Natural Gas 3',
Gallery1.Selected.GasMonth = GasMonth,
{
Provider: 'NG Provider'.Text,
Cost_GJ: 'NG Cost'.Text,
Monthy_GJ: 'NG How Many'.Text,
Admin_Fee: 'NG Admin'.Text,
Delivery_Fee: 'NG Delivery'.Text
}
) )
)
