Hi Raffe,
You can set the value of the RadioButtons as you want. Lets say you have set the values as 1,2,3,4.
Then in the click/change event of the radio buttons you can write the following script.
if (this.rawValue == 1)
{
TextField1.rawValue = "Anything you want";
}
else
{
TextField1.rawValue = "Anything you want";
}
For many options you can also use switch case statement.
Thanks,
Bibhu.
