Telepace Studio 4-20ma Scaling 0-100%

I am having problems Scaling a 4-20ma signal coming in from a valve showing the percentage the valve is open 0-100%. I have the low raw value coming in when valve is closed and I have the upper raw value. Is it best to just do some math functions to scale the raw analog value or use the scal function in Telepace. Could someone please show me an example on doing it with math functions in Telepace Studio or how to use the scale block function to do it? I need the end result to be stored as an unsigned register to display on the HMI. Thanks in advance

Never mind I got it working with a SCAL block and a FTOU function...pretty simple
