Hi @matthewd92
Sometimes i did not receive a from socket so it shown as '?'  which defines 'not a number' i think. 

Please refer attachments of errors. 

When i wanted to run the program, i have to go and make it zero manually in order to run.
How to make it as zero when i receive such errors.
Note:i cannot use previous program values for some reasons.

    The first return value in the list that is returned is the number of values returned, you can use this to check to see if there is anything returned.

    if a[0]>0:<br>&nbsp; b=a[1]<br>else<br>&nbsp;b=0<br>end<br>
