I posted this in the general developers forum a couple of days ago, but haven't got any resposes yet and as this forum now officially includes Applescript then here goes:

To 'introduce' myself to the Applescript language, I am writing a script that will create a web page based on answers to questions asked by the script.

In setting the background color, I would like the user to be able to select a color from a list presented to them.

<BLOCKQUOTE>code:<HR><pre>if the button_pressed is "Colour picker" then choose from list {"Red", "Green", "Blue", "Orange", "Yellow"}
with prompt "Choose a colour:" default items {"Red"}[/code]

As shown above, displaying the list of color options is not a problem. However, once the user clicks on 'OK', they will be returned to a dialog box, defined by the following:

<BLOCKQUOTE>code:<HR><pre>display dialog "Enter a background colour (as a hexadecimal value):"
default answer "FFFFFF" buttons {"Cancel", "Colour picker", "OK"}[/code]

My problem is copying the answer selected in the list into this dialog box so that the user can see that their choice has been recognised. A further problem is converting the items in the list into hexadecimal RGB values to display in the dialog box.

For example, in the first dialogue box, the user will be asked to enter a color value or pick from a list. Once the user has selected a colour from the list, I would like the script to display the color's equivalent hexadecimal RGB value in the original dialogue box. My questions are:

* How do I place the value returned from a list (the "choose from list" command) into another dialogue box?
* If the values displayed in the list are normal words, how do I get them to display their hexadecimal RGB values in the dialog box?

Thanks in advance for your help!

i guess i'm not really sure exactly what you're looking for, but hopefully this scriptlet will give some ideas:<BLOCKQUOTE>code:<HR><pre>property color_text : {"Red", "Green", "Blue", "Orange", "Yellow"}
property hex_Colors : {"FF0000", "009900", "333399", "FF6600", "FFFF00"}

if the button returned of (display dialog "Choose a color..." buttons {"Cancel", "Colour picker"} default button "Colour picker") = "Colour picker" then
set the_color to (choose from list color_text with prompt "Choose a colour:" default items {"Red"})
set i to 1
repeat with a_color in color_text
if (a_color as list) = the_color then
set color_id to i
else
set i to (i + 1)
end if
end repeat
try
set colorasHex to (item color_id of hex_Colors)
set colr_prompt to ("Colour choice: " & (the_color as string) & " (" & colorasHex & ")" & return & "Enter a background colour (as a hexadecimal value):")
set backg_colr to (choose from list hex_Colors with prompt colr_prompt default items (colorasHex as list))
if (backg_colr as string) is not "false" then
display dialog "Background colour choice: " & (backg_colr as string)
end if
end try
end if[/code]hope it helps,
