You can use the expression binding to accomplish that. Just bind the numeric text field to the following expression:`if(something = value, {_mine_/ne_pa1-6/ne_pa1}, {_mine_/ne_pa1-6/ne_pa2})`You just have to replace the something = value with an expression that returns the first tag if true and the second if false. Hope this helps.
