Hi All, this is about any component block that i use for my app. how to avoid duplicate emoji as screen shoot below.? ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/5/45b37f21155b9b575954564b3cd01375b25d118d.png) what i want for one label only can use 1 emoji at same time. Here is my block ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/c/6c7cb82631800876e30c09a59922dd8e4840eaf9.png) ---

You are joining the new emoji with the label’s text. So if the text already has an emoji, you’re going to have two. You need to join the new emoji with the **source** of the label’s text. What is the source of the label’s text? Did you type the label text in? Are you using a data source for that? If you typed the text in, then you’ll have to use the substring block and join the new emoji with the substring from letter #2 to the last letter of the label’s text: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/6/46fcb4dd02afb1e98f5314b5ae1991dd4eae5792.png) This will only work is there is _already_ an emoji. So you’ll have to check for that by using the “in text get letter #1” block. ---

The green “component” block has the ID of the label, which is a long string of characters (as seen in your screenshot). ---
