If/Then Statements

[IndeBlue]

I have read the available information for if/then statements, and it seems they are all regarding calculations.. 

I am here to see if there is a way to do "if this checkbox is selected, then allow this text field to be filled out" or even "if this text field has text entered, then allow this text field to be filled out"..

Place this as a mouse up action in the checkbox:

if (event.target.value != "Off") {this.getField("TEXTFIELDNAME").readonly = false;}
else {
this.getField("TEXTFIELDNAME").readonly = true;
this.getField("TEXTFIELDNAME").value = this.getField("TEXTFIELDNAME").defaultValue;
}
