Hello,

Could somebody tell me how to pass something from one function to another? For example, say I had 3 functions, one to get two numbers, one to add the two numbers together, and one to take that total and add tax to it. I'm trying to understand how to take the total from adding 2 numbers in one function and returning it to another to add tax to the total from the other function. I hope this makes sense. I'll post what I'm trying to do. This works ok until I try to add the tax function. Thanks. mcorn
