I guess the Excel component can't be used the way you try it. Input is meant for reading in the Excel file and Output for extracting selected ranges of that file. Look it up in the help. And while you are at it you may also look if WRITEEXCEL will do what you want.
Please post the worksheet, not just pictures - its hard to sometimes impossible to debug a pic. You attach any file by chosing "Use advanced editor! at the upper right. You then get the option to attach files at the bottom.
I guess that the cause for the error is the use of t as a range variable. So F(t) might look like a vector but it isn't.
Turn t into a vector, One way to do it is:
i:=0,1..Tp/0.1
t[i:=i*0.1
Chances are your first try with the excel component will work that way, too.
