strange syntax error in while loop

[laredotornado]

Hi,

I'm getting the error

SyntaxError in OrderController#confirm
/usr/local/apache2/htdocs/easyrx/app/controllers/order_controller.rb:
11: syntax error, unexpected kEND
end ^
/usr/local/apache2/htdocs/easyrx/app/controllers/order_controller.rb:
33: syntax error, unexpected $end, expecting kEND

in this method:

def confirm
i = 0
while params[rescription_number + i.to_s] != nil and
params[:description + i.to_s] != nil
session[rescription_number + i.to_s] =
params[rescription_number + i.to_s]
session[:description + i.to_s] =
params[:description + i.to_s]
i++
end # line 11
end

Thanks for your help, - Dave

i++
end

Ruby doesn't have the ++ operator and parses the above as binary plus followed
by unary plus, i.e. "i + (+end)". Thus the syntax error.

HTH,

Ruby doesn't know ++, so you have to write i+=1
