State Credit for property taxes: not accepting input data I input the numbers and then when I hit continue, it tells me to review it again. Not sure why...

I click all they way though, it asks for my paid property taxes and then there is a second box of nonresidential paid property taxes.  I put the values from my bill in the top box, and since I didn't have nonresidential property taxes I left it blank originally.  When it asked me to review it the first time I put 0 in the nonresidential box.  It's still asking me to review the Credit for property taxes and wont let me get past it.
