nothing happens when i type into the text box..
Jump to Postfunction callf(flag) <- this variable will need to be set somewhere unless you are declaring a global variable.
{is test(); supposed to be a function? if so is it returning a value?

}
Jump to PostThe point I was trying to make was that the variable flag was used within the function callf. Therefore does it need to be a global variable?
Once passed that stage you have to use function callf() not just callf() to define what happens within the function

You also have a line test() if this is calling a separate function then that will have to be visible somewhere within the code or an include.

you are right that your code would indeed return 'hi from else' but in the test that I had done I had set the flag variable to 0;
