Form, radio and text box

[burtybob]

Hi all,

 

I am trying to get it so that if i insert data into form field 4 then radio box 4 is automatically slept, however i can not find the right bit of code, the code i am using now works but it requires a lot more manual work from the user and i wish to do this so that A The user does not need to do as much to do the same job AND it lowers the chance of mistakes.

Please can any one help?

Thanks everyone,

Ben
