Razor declare and use variable syntax - asp.net-mvc

Question

I'm trying to get this razor template working but am having trouble declaring the variables for FDate1,2,3,4,5,etc... correctly.
For example I've just included the first FDate1 at the top. The lower part of my code is working correctly the looping part.
What am i doing incorrectly?
#{
string FDate1 = var row in AME.GridF18.FDate1("SubmissionID='" + TknParams.SubmissionID + "'");
}
<div class="table-responsive">
<table class="table table-striped table-condensed table-bordered" width="100%" border="0">
<tbody>
<tr>
<th colspan="7" scope="col">#FDate1</th>
<th colspan="2" scope="col">#FDate2</th>
<th colspan="2" scope="col">#FDate3</th>
<th colspan="2" scope="col">#FDate4</th>
<th colspan="2" scope="col">#FDate5</th>
<th colspan="2" scope="col">#FDate6</th>
<th colspan="1" scope="col">#FDate7</th>
<th colspan="1" scope="col">#FDate8</th>
}
</tr>
