Hello @ra2or
Thank you very much for using our plugin. I’ll try to describe the process with a hypothetical example.
Assuming the radio buttons field is the fieldname123, and it has a choice with value 888, and you want to tick/untick it based on another field, for example, the value of the fieldname2, as follows:
If the fieldname2 value is greater than 100 tick the choice, and untick it otherwise.
To implement this behavior you can use a calculated field as an auxiliary (you can hide it by ticking a checkbox in its settings) and enter the equation:
(function(){
if(100 < fieldname2) getField(fieldname123|n).setVal(888);
else getField(fieldname123|n).setVal(0);
})()
Note I used the |n modifier with the fieldname123 field to refer directly to its name instead of its value.
Best regards.
