```There were a couple of syntax errors:
in the summation with ebitda and in kinv0
Below is the corrected code.

wacc = ((rf + \[Beta] ((1 + tax) (d/(d + e))) (rf - rm)) (e/(d +

e))) ((rf + (1 - (NormalPValue[(Log[(d/(d + e))]/((d/(d +
e)) - 1)) (1/
stde)])) r) (d/(d + e)))
value = \!\(
\*UnderoverscriptBox[\(\[Sum]\), \(t = 1\), \(\[Infinity]\)]
\*FractionBox[\((
\*SubscriptBox[\(ebitda\), \(t\)]\ \((1 - tax)\))\), \(\((1 + wacc)\)^
t\)]\) + \!\(
\*UnderoverscriptBox[\(\[Sum]\), \(t = 1\), \(\[Infinity]\)]
\*FractionBox[\(\((
\*SubscriptBox[\(dep\), \(t\)])\)\ tax\), \(\((1 + wacc)\)^
t\)]\) - \!\(
\*UnderoverscriptBox[\(\[Sum]\), \(t = 1\), \(n\)]
\*FractionBox[\(\((
\*SubscriptBox[\(d\), \(0\)] -
\*UnderoverscriptBox[\(\[Sum]\), \(t = 1\), \(n\)]
\*SubscriptBox[\(d\), \((t - 1)\)])\) \((rf + 1 - \((NormalPValue[\((
\*FractionBox[\(Log[\((d/\((d + e)\))\)]\), \(\((d/\((d + e)\))\) -
1\)])\) \((
\*FractionBox[\(1\), \(stde\)])\)])\))\)
r \((1 - tax)\)\), \(\((1 + wacc)\)^t\)]\) - \!\(
\*UnderoverscriptBox[\(\[Sum]\), \(t = 1\), \(n\)]
\*FractionBox[\(
\*SubscriptBox[\(d\), \(0\)]/n\), \(\((1 + wacc)\)^t\)]\) - Subscript[
kinv, 0]
