You have your constants defined in the load event!

Move them out of there place them here:

Public Class Form1

Const decTAX_RATE As Decimal = 0.06D ' Tax rate
Const decWHITE_BAGEL As Decimal = 1.25D ' Cost of a white bagel
Const decWHEAT_BAGEL As Decimal = 1.5D ' Cost of a wheat bagel
Const decCREAM_CHEESE As Decimal = 0.5D ' Cost of cream cheese topping
Const decBUTTER As Decimal = 0.25D ' Cost of butter topping
Const decBLUEBERRY As Decimal = 0.75D ' Cost of blueberry topping
Const decRASPBERRY As Decimal = 0.75D ' Cost of raspberry topping
Const decPEACH As Decimal = 0.75D ' Cost of peach topping
Const decREG_COFFEE As Decimal = 1.25D ' Cost of regular coffee
Const decCAPPUCCINO As Decimal = 2D ' Cost of cappuccino
Const decCAFE_AU_LAIT As Decimal = 1.75D ' Cost of cafe au lait

Delete the form load event as you have nothing in there of interest
