Have found some great code in previous topics that ALMOST does what I need:
<span class=buttonborder><input class=button type=submit value="Save" onClick="if (confirm('Your Stand Price per Sq Metre is ' + 'variable' )) frmAdmin.submit(); return false;"></span>
I just need to get the syntax for the variable...I tried:
dict("StandPricePerSquareMetre")
with no luck, thanks in advance.
