hey everyone! I am getting data from an API and now I want to allow the user to Tweet the result. It’s working (thanks to this community) but I now need to limit the # of characters that can be sent to Twitter since the max is 280. I’ve posted a screenshot of the JS connected to the button where I am trying to limit the # of characters. It’s not giving me an error but it also doesn’t seem to be working. Any tips? ![Screen Shot 2022-06-07 at 10.06.27 AM](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/1X/b968246263aa56eb9799cfd675509e3c4f909e4a.png) ---

I am on my phone now but it looks like you are returning the original unchanged value. Line 3 you are encoding the `uri` variable and assigning it to the `encoded` variable. Line 5 you check the length of `uri` and assign a different value, but `encoded` is unchanged by this ooeration. Line 7,9 your return value is calculated from the variable `encoded` that is still unchanged. Try moving the code on line 3 after the code on line 5. On a side note “uri” and “url” are very easy to misstype, you can try to use more specific and different names. ---

thanks, I moved the lines but it didn’t seem to have any impact on shortening the text… perhaps it’s an issue with line 5 itself? ---

I think it should be: `if (uri.length > 250) { uri = uri.slice(0,250) }` ---

From your code the assumption is that `uri` is a string. You need to decide how to handle the case of `uri` being `undefined` as in this case. You can decide not to run the workflow at all or you can return a default value. You can add this logic with weweb formulas too. Without knowing the context of your workflow I can suggest only partial solutions. A dirty quick fix can be to add `uri = uri || ""` ---

Hi @nocodedevs 👋 You can actually do this with the subText no-code formula: ![CleanShot 2022-06-07 at 20.22.59@2x](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/1X/818b0a1a5bd99c95bb6237ec70518b34209cc9ae.png) ---
