Numeric input field and checksum calculation
I have the attached file and need help with it:
There are 4 input fields (numeric entries) per line. I want to restrict the input to 1-5; no other number should be possible.
Then a checksum shoul...
One way of doing the first part is to disable the UTS, and put an error message on another slide that shows if the entry is <0 or > 5. You'd evaluate the my variable you're already using for that purpose. Another way is to convert the entry silently. In any case, once you've got an acceptable value for the N numeric field, you repeat the process for the others.
I'd probably go with the silent conversion, but whatever you do, make sure you include a sentence above the chart that says how the input will be treated so that the user isn't surprised.
About the second part -- why would you run a checksum on the data? It's not going anywhere so there's no chance of corruption.
