Use Formula with my own parameter get from a Textbox tool

Alteryx Partner

Hey !

How is it possibly to work with parmeter from entry fields?

Text Box tool connect to a an Action tool and connect to a Formula tool
Input data tool (with a select * from mytable) connect to the Formula tool.

When I run the workflow I get the error:  

Formula (24)    Parse Error at char(20): Unknown variable "myentryfieldtext" (Expression #1)

How configure my Formula tool and my Action Tool?




My current configure:

Text Box



Action Tool

Hey Mathias,

In your formula you are trying to find the field called myentryfieldtext, this doesn't exist in you data set. What you need to do is surround it in quotes ("myentryfieldtext") then it will be recognised as a string. Once you do that then the updating action you are doing should work.

O.K thanks it works.

One Question at once:

When I connect a Browsetool at last I get not the right output.


When I use a Output Data tool an write the output into a csv-file. I get the correct output.

I'm not sure why you would get different answers between the browse tool and the csv output without actually seeing what is happening and what is going wrong.

Hey Paul!


I will you descripe what is going wrong:

1. my workflow




The formula expression is result = Contains([vorname], "mytext")

I start run as analytic app with the input parameter: mytext := Matt from the Textbox tool

2. output csv-file


3. output browse tool



You see the diffrence between output csv an output Browse tool?

I did not understand why the diffferent output was generate.

I couldn't replicate your error. I have a question though, what are the select tools doing?


I set up the formula tool to create the Result field as a Boolean and it worked fine to both the Browse and the csv. The only thing that I can think of is that the Result field is becoming a Boolean after the split and or something funny like that. Try having one Select tool go to both outputs. Otherwise, if the select tools just remove fields, then put one select tool before the formula tool and have everything performed in the formula tool.

I have you attach my workflow with required data in a Text Input tool.

Now you can take a look on it.

I only get always the similar output as I have post.

Hi Matthias,


The browse tool in the canvas will always have false when you hit the green start button as it is looking for "mytext" in the name. When you run it as an app, the correct text replaces "mytext" and so you get the expected results.


To test the browse against the output tool, select the browse tool in the interface designer and then it will appear on the output of your app for you to look at.

Hi Kane,


thanks for your supprt.

I get the same output results too.


It is not possible browse tool and other tools required for an app work together by running workflow only.

In is only works correctly by running as app.




I mean, it's like this
