RoboTask forum

Thank You oleg for your answer on "trigger 3rd tue of month".
Do you have an algorithm to perform a task every other week
reguardless of which day IE: week 1,3,5,7,9,etc. without checking the week# 52 times.
 

There is WeekOfTheYear system variable
You can calculate whether WeekOfTheYear is odd or even.
Use Evaluate action (in Basic group) for this purpose with the following expression
{WeekOfTheYear({Date})} mod 2

if expression is 0 then the week # is even, otherwise - odd.

algorithm will be such:

evalate {WeekOfTheYear({Date})} mod 2 // and save to Num variable
if {NUM}>0 then
   ...
   do something
   ...
end if

Thanks again Oleg,
I founf the evalate and the {WeekOfTheYear({Date})} but i could not find any wat to check for even/odd.
where can i get a list of modifiers like the "mod 2" used here? 

You should install additional Basic plugin.
Download here.
You can find the full help of built-in Basic. Press F1 in action editor (for Evaluate and Basic Script actions)

See the example below:
