Might you have the variable "NULL" set to an empty string somewhere?

good luck

>The code is executed. However, the value for that blank row is empty and not null. Does it mean, that the comobobox with the array as rowsource can not have a null value inserted? Should I try to replace myself the empty value with NULL? Do you have ideas what could be wrong?
