Hi NI community, I need your help with deleting the row headers of a table. The first time the program runs everything is OK. However, when the user sets a new number of tests and clicks the ‘Run Again’ button the old row headers not only are not being deleted but the new ones are appended under them. I would like the entire table, headers including, to be deleted and the new results to be displayed starting from the top of the table. I am attaching a sample program. Thank you in advance for your help.

You need to initialize your first shift register )inside the first sequence frame). Even better, simply use autoindexing to create the array, no shift register needed. Also note that writing the header does not belong in a loop, writing them once is sufficient. Use the proper datatypes. For example the number of trials is an integer. You have way too many unecessary local variables and sequence structures. most are not needed.
