Assign a name based on values

Question

I can't figure out how to display a name of a field based on values.  Here is what I have:
{SEAT_RECORD.TAX_TOTAL1}
{SEAT_RECORD.TAX_TOTAL2}
{SEAT_RECORD.TAX_TOTAL3}
{Tax.ID} - IDs are 1,2 and 3
{Tax.NAME}
I want to assign the {Tax.Name} to the the corresponding {SEAT_RECORD.TAX_TOTAL#}.
I have 3 IDs in Tax.ID (1,2,3). I want to create a text field with the appropriate tax name. {SEAT_RECORD.TAX_TOTAL1} corresponds with {Tax.ID} 1 and therefore should display {Tax.NAME} where {Tax.ID} = 1.
Same for {Tax.NAME} 2 and 3
On my Report I would like to have something like this in the footer section.
(TaxName1) {SEAT_RECORD.TAX_TOTAL1}
(TaxName2) {SEAT_RECORD.TAX_TOTAL2}
(TaxName3) {SEAT_RECORD.TAX_TOTAL3}
Do I need to create a formula or SQL expression? Any help will be appreciated.
Thanks,

Answer 1

That doesn't work...my footers look like this then...
Group Footer #1a: {Tax.Name} {SEAT_RECORD.TAX_TOTAL1}
Group Footer #1b: {Tax.Name} {SEAT_RECORD.TAX_TOTAL2}
Group Footer #1c: {Tax.Name} {SEAT_RECORD.TAX_TOTAL3}
and the output is pretty crazy.
I need to be able to create a variable like
Set @Tax1 as {Tax.Name} where {Tax.ID} = 1
That way I can just put the variable on a footer along with {SEAT_RECORD.TAX_TOTAL1} and get what I need.
