Go to the line in your file that the compiler is flagging error on. Start looking for odd things immediately before it. Like a missing } for instance.

Also, learn to indent your code. It makes spotting such things easier.

iHutch105 said you must not do this. That is, you must not have any statements between the closing bracket of the if block and the else.

if (condition)
{
   // do stuff
}
// do more stuff here
// and even more stuff
else
{
   // do else stuff
}

You have done this somewhere.

You also changed all your else if to else. I think you should change them back.

[GRex2595]

Right after your first if, you have statements.

you cannot have if, else, else. You need if, else if, else.

Just to reiterate what vin said.

wow I see it now. THANKS GUYS!!! now the only problem I have is the total issue. I need to sum up all the totals of each ptoduct. then I need the total cost to be multiplied by the cost of each item. I thought I did it right but it doesnt add at all. Ive spent all day staring at this program and I didn't even notice that simple error earlier so Im sure this one is staring me in the face too but I just can't see it. THANKS GUYS FOR ALL THE HELP!!!!!
