My workflow (see attachment) is triggered as soon as the expected weekly turnover is changed in the companies module to an amount higher than 0. After that, a function (see attachment) must ensure that this amount is copied to the registrations module. Only I get the following error:
Value is empty and 'tolong' function cannot be applied at line Number 7
When I run the function by clicking 'save and execute', it works. This same function also works fine when copying other fields between different modules. Do you have any idea what I can do about this?
