Nothing because it was in a completely unnecessary attachment (some 
people won't even receive it), so here's the code.

Stat = {'Vbatt': 51.24, 'Ichrg': 6.75}

print '   <td style="text-align: center;">SOLAR PANEL VOLTAGE</td>'
print('    DSB "HI;" %s') % (str(Stat['Vbatt']))
print('   <td style="width: 50%; text-align: center;">%s</td>') % 
(str(Stat['Vbatt']))

He also didn't bother specifying the actual problem,but like others here 
we just love guessing games.  So I'll go for:-

TypeError: unsupported operand type(s) for %: 'NoneType' and 'str'

Print in 2.7 is a statement so the first one is fine.  The second (and 
third) you're trying to apply the % operator to the print statememt 
which by definition is None, hence the error.  You also don't need the 
call to str so put it all together it simply becomes.

print '    DSB "HI;" %s' % Stat['Vbatt']

I'll leave you to come back with the next problem as I haven't worked 
out what the solution is yet :)
