Modification in program using CR6 dataloggers, 12   strain gauge vibrating wire (Geokon Model 4100), and AM 16/32B Multiplexer.

Hi there, 

I am using CR6 dataloggers, 12   strain gauge vibrating wire (Geokon Model 4100), and AM 16/32B Multiplexer.

I have created a program using the shortcut method using Loggernet software.this program doesn't work for me

Here is the program

'CR6 Series
'Created by Short Cut (4.0)

'Declare Variables and Units

Can anyone help me, Any Quick and easy solution for the program?

how to modify the above program in CRBasic Editor?

Thanks.
