Analytic App: Stop condition output If no data entered in the text box field

[NatashaSuello]

Hi,

I have a large volume of data records that I will use to search in using the analytic app (text box).

How can I set a condition to stop rendering the output if there's no data entered? 

I have 3 data fields to search in.

Let's say, Location table & Color table only has 10 records

while the Fruit table has 100K records. 

These selections are not mandatory/need to be filled in. 

My requirement is, I want to key in search in the Location with 10 records only,

the Fruit table with 100k records should not render any output since I didn't enter any data in the fields. 

It's like stopping the condition/ should not execute if there's no data entered. 

Thank you.

Look at the Error Message tool! Error Message Tool | Alteryx Help

You would write an expression to where if it's true, the error message should pop up. In this case, something like IsEmpty([#1]) or whichever stream the textbox is coming from.
