Need help with choice field not selecting other choices. It automatically selects back to the first option regardless of what choice I select.

[John Clyde Ap_a]

Hello, I have this field in my form that has been dynamically added through a client script

My current problem is that it won't let me choose other choices, for example when I choose Medium or Large, it just reverts back to small automatically. This goes for other records in the table too. 

Here is my script

function onChange(control, oldValue, newValue, isLoading) {

	if (isLoading) {
		return;
	}
	
	if(newValue == ''){
		g_form.clearOptions('u_choice_2');
	}

	var choice = g_form.getValue('u_choice_2');
	var ref = g_form.getReference('u_reference_1', callBackMethod);	// reference field name here
	
function callBackMethod(ref, choice){
	//g_form.setValue('u_choice_5', 'Small - '+ref.small+' '+'Medium - '+ref.medium+' '+'Large - '+ref.large);
		// give field name here
	g_form.clearOptions('u_choice_2');
	g_form.addOption('u_choice_2',ref.small ,'Small - '+ ref.small);
	g_form.addOption('u_choice_2',ref.medium ,'Medium - '+ ref.medium);
	g_form.addOption('u_choice_2',ref.large ,'Large - '+ ref.large);

}	

}
 

Please help, I cannot figure out what is causing it.

Hi,

I'd recommend following Kieran's advice to learn how to troubleshoot.

However, just looking at your code, your callback function is clearing the choice field, then resupplying it with the 3 values...which, without a "none" is going to default to the first choice, which you have as small.

So you'd need to review your code and think through what you're trying to do. Why onChange would you be clearing all options, then adding all 3 back everytime that field changes value.

You're doing nothing with the "choice" parameter in your callback function.
