Thanks for all your help. In the last few days I have had several questions about problems I have had and the answers have been great which shows this list is very much alive and well. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Saturday, July 15, 2000 9:23 PM To: [EMAIL PROTECTED] Subject: [REBOL] Error explanation Re: [EMAIL PROTECTED] wrote: > > Please explain this error I get: > > ** Script Error: val needs a value. > ** Where: val: first params switch/default type?/word Do this - val: print "" You get the same error, because print doesn't return a value, and Rebol needs a value to set val with. >> type? print "" == unset! So when layout parses your code, when it reaches 'area print data', it sees that 'print data' is a function, tries to evaluate it and get the result. But print returns no result, so it bombs. The second problem is that the data variable is a block, and you want it in string form. So replace print with form - view layout [ text "Directory contents:" area form data ] That's very basic, and puts everything on one line. So lets use a function that will put each entry in the block on a seperate line, and this is what you end up with - REBOL [] block-to-lines: func [blk /local result] [ result: copy "" foreach line blk [ repend result [line newline] ] result ] ftpaccess: layout [ backdrop 0.128.0 title "Pauls FTP Access" 255.255.0 text "Enter Host Address/Directory" hr: field "127.0.0.1" text "Login Name" ln: field "administrator" text "Password" Pw: field "testpwd" button "FTP Access" [ ftpurl: join ftp:// [ln/text ":" pw/text "@" hr/text] data: read ftpurl view layout [ text "Directory contents:" area block-to-lines data ] ] ] view ftpaccess If you ever do need to set a value as unset, do this - >> set/any 'val print "" >> value? 'val == false Julian Kinraid > I get the above error when executing this script I created: > > REBOL [] > > ftpaccess: layout [ > > backdrop 0.128.0 title "Pauls FTP Access" 255.255.0 > > text "Enter Host Address/Directory" hr: field "127.0.0.1" > text "Login Name" ln: field "administrator" > text "Password" Pw: field "testpwd" > > button "FTP Access" [ > ftpurl: join ftp:// [ln/text ":" pw/text "@" hr/text] > data: read ftpurl > view layout [ > text "Directory contents:" > area print data > ] > ] > > view ftpaccess
