[Haskell-beginners] Problem with do statement

[Michael Litchard]

I received an error message that might be due to indentation,
and not what the error message claims.

Here's the error, then the code. Below that I have some comments.

ghc --make CreateSession.lhs
[2 of 3] Compiling HtmlParsing      ( HtmlParsing.lhs, HtmlParsing.o )

HtmlParsing.lhs:81:5:
    The last statement in a 'do' construct must be an expression:
    let makeIDPage = do { initial }


> generateResourceHtml :: Curl -> String -> String -> FilePath -> IO (Either String String)
> generateResourceHtml curl user pass ipFile = do
>   urlSequence <- popURLrec ipFile
>   let makeIDPage = do
>       initial = urlInitial urlSequence
>       login = urlLogin urlSequence
>       flash1 = urlFlash1 urlSequence
>       flash2 = urlFlash2 urlSequence
>       showWebForwards = urlShowWebForwards urlSequence
>       quickCreate = urlQuickCreate urlSequence
>       getResource =  urlGetResource urlSequence
>       curlResp curl $ initial method_GET
>       curlResp curl $ urlLogin urlSequence $ loginOpts user pass
>       curlResp curl $ urlFlash1 urlSequence resourceOpts
>       curlResp curl $ urlFlash2 urlSequence resourceOpts
>       curlResp curl $ urlShowWebForwards urlSequence resourceOpts
>       curlResp curl $ urlQuickCreate urlSequence resourceOpts
>       curlResp curl $ urlGetResource urlSequence resourceOpts
>   runErrorT makeIDPage

It seems to me the first do construct ends with a statement,
 runErrorT makeIDPage.
Also the second do construct ends with a statement as well,
>  curlResp curl $ urlGetResource urlSequence resourceOpts

So I'm either wrong about what the definition of a statement is, or
this problem is really about indentation or similar.

Clarification?
