This time i wrote a code for unit conversion. For menu options i used the idea of “Sounds Plus” Example of codea but i enhanced it. Demo video and source code can be found in http://www.knowhowto.com.au/coding-of-unit-converter-using-codea
It seems that we have one more utility program. You might send your code to Codea Competition #3 @Zoyt.
Thanks Simeon and Sanit. i tried my best. next time i will do even better i hope @sanit i might send it to competition but dont know how to 
Thanks! Entry #2. I still need a few more… Thanks!
Is the link mentionned above unavailable ?
If so is it possible to share the code another time for the Codea community ?
Thanks in advance unless your code is still in competition as mentionned above.
Sorry the link isn’t available now. Here is the code.

I deleted all the blank posts - please check that I didn’t inadvertently delete something important.
Great work, thanks for sharing.
Thanks the Textfield class save hours of coding!
You are welcome edwin809. I tried to implement cursor effect in it but didnt work well though. May be u can try.
