How do I populate a text box based on the state of one of thee radio buttons?

[brettf69819018]

For example:

If radio button 1 = true textbox 1 = "option1"

If radio button 1 = false textbox 1 =""

If radio button 2 = true textbox 1 = "option2"

If radio button 2 = false textbox 1 =""

If radio button 3 = true textbox 1 = "option3"

If radio button 3 = false textbox 1 =""

all of the radio buttons = false the Textbox 1 should = ""

Sorry, they are not radio buttons, they are check boxes

What if more than one of the check-boxes is ticked?

[brettf69819018]

if checkbox1 is true then the code needs to ignore checkbox2, and checkbox3, and texbox1 = "Opion1"

if checkbox2 is true and checkbox1 is false then the code needs to ignore checkbox1, and checkbox3, and textbox1 = "Option 2"

if checkbox3 is true and checkbox1 and checkbox 2 are  false then the code needs to ignore checkbox1, and checkbox2, and textbox1 = "Option 3"

It is an either or situation

In that case you should give all the fields the same name but different export values, so they are mutually exclusive.

Then writing the code will be much easier, too...

This might work....??? But it is based on only one box being checked and will uncheck the other boxes

// Check box 1 is checked
if (this.getField("checkbox1").value == "On") {
    // Uncheck box 2 & 3
    this.getField("checkbox2").value = "Off";
    this.getField("checkbox3").value = "Off";
    // Set text field to Option...
    this.getField("textbox1").value = "Option1";
}
// Check box 2 is checked
else if (this.getField("checkbox2").value == "On") {
    // Uncheck box 1 & 3
    this.getField("checkbox1").value = "Off";
    this.getField("checkbox3").value = "Off";
    // Set text field to Option...
    this.getField("textbox1").value = "Option2";
}
// Check box 3 is checked 
else {
    // Uncheck box 1 & 2
    this.getField("checkbox1").value = "Off";
    this.getField("checkbox2").value = "Off";
    // Set text field to Option...
    this.getField("textbox1").value = "Option3";
}

There's no need to reset the other fields if you simply give them all the same name, as I've explained.

This worked thanks, I modified I a little but it put me on the right track.
