Invalid Input error: Suggestions?

[Ben Fairbank]

Thanks for earlier suggestions about maximum number of variables in a LOCAL statement. Having fixed that, I move on to thornier errors. When attempting to run the program I now get the message "Probability2 Error: Invalid Input" (the program name is Probability2). I have searched for a discussion of the Invalid Input error and found discussions that mention invalid variable names in LOCAL statements and the misuse of INPUT statements. I have scrubbed and/or changed variable names in the LOCAL statements and have no INPUT statements. Any thoughts as to where I might look next for the problem?
Again, thank you for suggestions.
