Hi guys,
In my application I have several variables that I would like to present in a label, according to the text of another label, which is randomly changed during operation.
As there are many, I would like to build the name of this variable from the text presented, instead of using a huge sequence of If statements.
See this example to illustrate:
Can any of my colleagues help me?
Thanks in advance.
Post all relevant blocks (and the aia).

Thanks for the quick response @Anke,
I apologize if I was not clear enough in my presentation.
Here are the blocks relevant to my problem and my complete project file for your study.
Layout_2.aia (934.1 KB)
just use the text getter property of the corresponding labels
for example

Thank you @Taifun,
Ok, but can you show me how to apply the text returned in the get.variable block, when Lable1.Text is one of the 3 available variables names (Data1, Data2 or Data3), as my example?
The get Label1.Text will always return the text of that label, no matter how you set that text previously

I recommend Chapters 19 and 22 from
http://www.appinventor.org/book2
Also see the introductory articles at
concerning table lookup.
Thank you so much @ABG ,
I will carefully study the documents you suggested. I'm sure I'll find the solution there.
