I have jsut got on to haskell, and am having some real difficulty with it.. and was hoping that someone could help me out with this.
 
 
Now i am sure that this isnt the page that i'm meant to put stuff like this, but it might be somewhere that someone checks and might see..
 
 
Variable are as followed:
 
 
type KeyNum = Int {- unique id -}
 
type Station = String {- Station Name -}
 
type Interchange = String {- Interchange stations -}
 
type DurMins = Int {- Duration Mins -}
 
type DurSecs = Int {- Duration Secs -}
 
type Database = [ (KeyNum, Station, Interchange, DurMins, DurSecs)] {- Record Structure -}
 
 
right.. now when i try and enter data into the Database i get the following error
 
 
ERROR file:.\HaskellSample1.hs:20 - Syntax error in declaration (unexpected `::')
 
 
Now on line 20 the code is doing the following:
 
 
TrainTimes :: Database
 
 
now according to the haskell book i have.. this should all be fine.. but for some reason it is erroring on me.
 
 
If you have any clues, and can help me please can you contact me on the following email address.

All help will be greatly appreciated..
