IF Statement; Display value X or X1 in Label based on Y or Y1 value from a tableview cell subtitle

I have a label in my view controller that should display a price (3 or 4.5) based on the value displayed in a subtitle from a tableviewcell.

I want to implement the if else statement in my label (AmountTwo) but struggle to.

If I pick on the slider the a cell it transport it to the mainviewcontroller and shows name and size.
