URL Encode question

Try this
"http://elines.coscoshipping.com/NewEBWeb/public/cargoTracking/cargoTracking.xhtml?CARGO_TRACKING_NUMBER_TYPE=BILLOFLADING&CARGO_TRACKING_NUMBER=" & URLEncode("REDIRECT=1&uid=" & [your tracking number field])

has problem, the website will be :
http://elines.coscoshipping.com/NewEBWeb/public/cargoTracking/cargoTracking.xhtml?CARGO_TRACKING_NUMBER_TYPE=BILLOFLADING&CARGO_TRACKING_NUMBER=REDIRECT%3D1%26uid%3D6157691370

The number did not encode the right place

Try this
"http://elines.coscoshipping.com/NewEBWeb/public/cargoTracking/cargoTracking.xhtml?CARGO_TRACKING_NUMBER_TYPE=BILLOFLADING&CARGO_TRACKING_NUMBER=" & [your tracking number field]

without last "REDIECT=1&UID="  The website does not show it correctly 

and some web. need encode two numbers at two differnt place, it's also one question 

The problem is that the website will now allow you to do that.  Even if you paste in the URKL that you see after you do a search, it does not work.  So trying to replicate that URL will not be successful.

Try it. do a manual search and observe the URL.  Copy and paste it manually and you will see that it does not work

I am guessing this is the type of URL formula field you are looking for:

"http://elines.coscoshipping.com/NewEBWeb/public/cargoTracking/cargoTracking.xhtml"; &
"?CARGO_TRACKING_NUMBER_TYPE=" & URLEncode([BILLOFLADING]) &
"&CARGO_TRACKING_NUMBER=" & URLEncode([CARGO_TRACKING_NUMBER]) & 
"&REDIRECT=1" &
"&uid=6157691370" 

You are better of formatting a URL formula with one query parameter per line even in situations above the last two parameters are constants and could be written as one string:

"&REDIRECT=1&uid=6157691370"

You may think you are shortening the formula if you do this or you may not think you don't need any greater generality but you will just be making your formula more difficult to read and maintain in the future.

I figure it out
thanks a lot
