Texting with app developer

How can I see the number that I was texted from and use it to text that number to a different number

Use the Texting1.MessageReceived event block to get the number the text was from. you can then pass this to a variable for reuse.

thank you! also, I am new to mit app developer. Do you have any place that you recommend I can read up on it?
Thank you!

Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor’s Manual here in the AI2 free online eBook http://www.appinventor.org/book2 … the links are at the bottom of the Web page. The book ‘teaches’ users how to program with AI2 blocks.

There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
