Uncheck a box

[Jack157F]

I have two checkboxs. If the first is not check, the second can't be checked. Based on the value of the fist box I would like to turn off the second box.

v1=getField("First Box")

v2=getField("Second Box")

if (v1!="Yes" // how do I uncheck v2????

Thanks all.

If you want to disable second checkbox while first checkbox is not checked use this as 'Mouse UP' event of "First Box":

this.getField("Second Box").readonly = event.target.value == "Off" ? true : false;
