What do I do when compare the Nickname(User input) and the other input Nickname that already entered in Airtable? if I have the same, I want to output an alert, if I don’t have one, I want to enter it into the DB? ---

There are a few problems with your latest screenshot: 1. You are initializing NNick to an empty text string ("") but then assigning it a column object value. Delete the “” text block from the initialize block. 2. You can’t compare a text input value, which is a text string, to a column, which is an object. You need to get a property/cell from the column and then compare that to the text input value. 3. Alerts need more than a Title value to work properly. See the documentation or tutorials by Googling _alert Thunkable_. ---

I think that the green “column” gives a list. It contains all values of the columnName “Nick”. Please try a list operator like “if does list (column) contain (NickInput’s Text)” → do alert … ---

1. IS “null” ok instead of “” ? 2. Please advise me how… or give me example ?? ---

No. `null` is **NOT** the same as “” `empty text`. **[Edit]** Because the `green block column` is actually a **list** your blocks will not work. You need to loop through all the entries in the `green block column` and check the entries one by one. ---

You don’t need to initialize the variable to a value. Just leave the block open/empty. ---

Three problems. 1- Remove `List component` in the block `set app variable NNick to`. 2- Remove `get property ..... of object`. It should be `If j = app variable NNick`. 3- `set Alert1 Title` should come before `Alert1 Show`, not inside it. ---

I agree. Each of your posts is “Error happens” or “Not working.” We need to know more than that to be able to help you. It helps if you explain what you expect to happen and what actually happens when you preview the project. ---

alert not shown… ---
**Author:** ![muneer](https://sea1.discourse-cdn.com/flex015/user_avatar/community.thunkable.com/muneer/32/75210_2.png) [@muneer](https://community.thunkable.com/u/muneer)\ **Post date:** [September 1, 2021, 5:41pm UTC](https://community.thunkable.com/t/if-nick-name-is-same/1462796/18 "2021-09-01T17:41:36Z")
There are many reasons that would prevent the `alert` from showing. A simple reason if the Nick name in the table is **Muneer** but the user typed **muneer** (notice the first character “M” is upper case in one side and lower case in the other) the test condition will fail and to the app they are **NOT the same** and therefore the `alert` will not show. Another reason is your Airtable connection has an error therefore the `column` block will be **empty**. ---

You should add blocks to your If/Else block so that you can better understand what is or is not working. Right now, your “if” block condition results in either an alert being shown or nothing happening (setting a text input block’s value to it’s value does nothing). Instead, change the value of a label or text input to something you’ll recognize like “j=text input” and “j≠text input”. Then you can preview and see where the program is getting stuck or whether it’s evaluating the if/else condition as true or false. ---
