Custom Field issue

[psvialli]

Hi,

I am trying to have a selection drop down box so the customer can select 10 colors.

I have set up a Custom Field and set it to String

But when I look at the product and add in the Custom field I get this  Price & Value ?  no option to add in Text  - have deleted and tried 5 times recreating it as string but does not seem to work.  Am i doing something wrong as all i am trying to do is have an option for the customer to select a color.

Selection i get
Title                    Price      Value
String Colour   0.000000     £
