I have the following form:
and when I run my app, I get a SQL error that tells me that I need to declare a value for '@payperiodstar tdate' but I know that that value is declared because the first query runs fine. I am told that the line where the error is is line 59, which is this line:
Can someone please assist me with this error?
Thank you
