Just did the test and it works perfectly.

All the above answered my Original question.
So case closed, problem solved.
But. . . .

I want to add an other control to the template.
The field you named "SAP nummer", I call it Personeelsnummer (employeenumber) has to have exeactly 8 digits.
If the number has less digits the user has to add zeros before the number.
So 1234 becomes 00001234 or 123456 becomes 00123456.

Is there a way I can get the user to do so and also that he can not save the template if the nmber is not 8 digits long?
