Computing Cost

[Jay V.]

Hey, all!
I am running into trouble with some code I am doing for an assignment.
The section highlighted in red is the section that I am having trouble with.
When the user selects a seat type and then clicks the compute button,
the wrong cost is displayed instead of an accurate cost.

Is there any way I can fix this issue?

Option Strict On
