No need of an error cheking.
This is included in the language, if you use a begin... end statement
If price2 > 0 then
Value1 = (price1)/ (price2)
Else Value1 =Value1[1]; <=======Firts, you do not need this. It is implicit
(variables are updated from previous value as default)
If price2 <> 0 then negin
Value1 = (price1)/ (price2);
end;
Does the trick.
If f price2 <> 0 is false, the calculation after "begin" and before "end" is
not executed and value1 remains with the same (previous) value, that is
equivalent to your error code checking.
