IF (condition) THEN (result := )

If (condition): user can use any normal
operators or formulas which can be insert in (condition). When the condition is
true, It will give the result.
Tip: condition can be isolated in parentheses ( ) to organize better (not necessary but good practice)
If ([property]<0)
If ('[property]' = 'Text')
If ([property]=10)

Then (result:=): this is the result of the if statement when the above condition is true. User can use any normal operators or formulas here.
Caution: the returned value for the result will need to share the same type, being either a text or number, with the "inheritedfrom" property.
Then (result:=[property])
Then (result:='[property]') (when the property type is a text)
Then (result:=[property]10) (when the property type is a number)
Example 1: if a equals 10 then d will be 100
Example 2: if a equals 10 then d will display "It is correct"
Example 3: if a is text then d will displays "It is correct"
