Always use the value "" as your input for startstring.

This is my Custom Function and I want to edit it


I used this function in combination with a Dialog_PlugIn ( to display a dialog with a "combobox" in which the user could select a value from a drop-down list. First the DeDupe was used to set a variable, then an external function from the plugin was used to set the values for the dialog, then an external function displayed the dialog. I hosted the file with the script on FM Server and it worked fine in combination with FMPA 11 on my windows 7 laptop. Now another user ran the script from the hosted file on a MAC using FMP 10 and got the error "the maximum number users are currently using this copy of Filemaker" at the moment the dialog should appear. So setting the variable was not a problem, and using the list to set the values did not create an error. Only the moment it should present the dialog to the user it went awry.
