Dear all,

We are using a program without registration (Event) to create a survey at country level.

In the form, we therefore have several questions type Yes/No or Yes/No/Unknown, and we would like to easily create maps showing countries which have said No in red, the ones which have said Yes in green and the unknown in grey.

We tested several solutions:

1. 

```
 Yes/no type

```

2. 

```
 Option set text type Yes/No/unknown

```

3. 

```
 Option set integer type 1/0/9

```

The third test DE works well and we were able to represent the countries based on the value of this event DE.

We therefore applied the option 3 to all the DE which were expecting a Yes/No/Unknown answer.

But then I was not able to replicate the maps. I tried again today and I get the following error:

Code: 409  
Status: Conflict

Query item cannot specify both legend set and option set: Ji8JOyk9YuE.

Any idea?

Lise.
