‘I am trying to write info for 21 days. I am reading from a ‘;’ delimited txt file that contains column headers and 7 days of info. I read info from a file and establish 7 variables (one for each day of the week). I print the variables after creation and they are correct. When I try to use these variables later in the program over a 3 week period (21 days) only the first variable contains data. Any ideas?’

Any ideas why the values of PerfDay2 thru PerfDay7 become blank?

Upon reusing the variables only the first one contains data, the next 6 are empty.’
