What are you trying to accomplish?

Do you need a function or a sub? A function returns a value with a statement at the end like: Pos = rResult.

Hi Guys sorry for the delay in answering,

What I am trying to do is when a value is changed on the screen i take that value and run it through a script, in the script i want a function or sub to take that value and do some math on it and then transfer that value into a DB. However I will have many of these values on the screen and I wanted to call the same script but have many different functions in it so i can make the relevant calculation depending on which value from the screen was change and therefore which function/sub was called.
Thanks (hope that makes sense)

Not sure about the advantages of using only one script to perform multiple functions but if that's what you want to do, declare your script as a sub not a function, pass the Item number to the sub and then use a case statement to perform different statements depending on the item edited.

Thanks for the advise,

Got it working I declared the function as a sub but in the script declared it again using function sub, end sub etc This was wrong i took these out and got the script to work> The reason I multi functions in one script was they were all the same calculation so i used different case selects.
Thanks for the help.
