Why do I have to keep typing column headers and put a numeric value everytime I open my saved VI? Can someone please help me solve this problem?

[GRC5000]

I built a VI that opens three workesheets on excel with random number used as data. The first two worksheet are similar and have column headers "Thermo 0 and Thermo 1". The third worksheet has three column headers "Thermo 0, Thermo 1, Ambient". But if I close my VI and reopen it. The column headers and the numeric value are blank. How do I solve this problem. I attached the VI.

This is how I want my VI every time I open it. 

Instead this is what I get every time I open it:I don't want this

The problem is that the default value for your header control is an empty string.  If you don't want to lose the string values Thermo 0, etc., you can make that control a constant or you can enter the desired strings, right click on the array control and make the current value the default.

Use edit->set as default values
