required radio buttons

Search your help for 'Exclusion Group'. The two radio buttons must be in a single Exclusion Group.

ok opened acrobat 8 searched for Exclusion groups. nothing found
im using acrobat 8 pro on mac if this makes a difference?

Maybe you are using Acrobat forms instead of Designer. In the Help of Designer, it explains it. I'm not familiar with Acrobat forms.

yes im use acrobat forms. do you know anyone that is familiar with acrobat forms? or where i mite go?

I'm also trying to figure it out as well. I am using a Acrobat forms and a mac as well. Can anyone please help???

Since the "required" property for check boxes or radio buttons requires a response on the widget level, individual field, and one can not set the "required" property on a widget level, one will need to create a script to set or unset the "required" property for check boxes and radio buttons when an item is selected or there is no item sleeted. Since this action will need to be applied to each check box or radio button group, one could write a document level JavaScript or function.

A check box or radio button group will have the export value of a selected button or a value of "Off" when no item has been selected. This fact can provide the information to create the statement for an "if" statement for a general test to see if an item has been selected or not.

Using a document level function to test a value against "Off" and return the logical result could be used to set the "required" property:

// Document level function
function ButtonRequired(cValue)
{
/*
Function: return result of comparison of passed value to 'Off"
Input: cValue
Return; logical result of comarsion of passed value to "Off"
*/
if (cValue != "Off") {
return false;
} else {
return true;
}

return;
}
// end function

The on blur action could then run the following JavaScript:

/*
on blur action:
set required property on comparison of the field value to "Off"
*/
this.getField(event.target.name).required = ButtonRequired(event.value);
// end on blur action

Thanks! it worked. Just one more thing, I have one question on my form that has multiple radio buttons for the same question. (not just 2) How can I apply this javascript so that it works with more than 2?

Nevermind it works as is. But now I have a last question! :)

I want when I hit my reset forms button for all the buttons to default back to required.

Thank you thank you thank you - I've been struggling with radio buttons and how to make each set required, and your script and explanation worked perfectly.

thank you!

i think this will work for me, but i still have no idea how to do it. my radio buttons are Yes and No answers and there are several of them. how can I apply this to my document?

i know basically NOTHING about javascript, so even with all the code up there, it makes no sense to me.

i'm using acrobat 8 pro and i'm on a mac.

thanks!
