[Tex/LaTex] Double superscript error


I'm a relative beginner with Lyx. When I type in this code I'm hoping for T' to be followed by superscripts and subscripts. Instead I get a "double superscript" error when I try to view the pdf


Any idea how I can fix this?

You can insert \prime symbol as part of the superscript ^{...}, rather than having "two superscripts":
