Hi I just started to learn navision and came across one problem. I'm trying to add a control (checkbox) on a form and specifying the following in the properties:

Caption: 'Blocked'
SourceExpr: 'Blocked'
ShowCaption: Yes

When I compile the form, I'm getting this error message " The control () has an invalid data type option. The valid data types are : Boolean, BLOB."

Same is happening with the option control. I'm doing everything as in the training manual. Also tried to copy and paste a checkbox from another form which works. But it still gives me the same error. Spent 2 hours with no result. Please HELP...

In the table is the field your checkbox references the right type i.e. a boolean?

Do you mean the SourceExp property? I set the SourceExp to 'Blocked' as said in the Training manual...

You need to set the SourceExpr to a boolean type variable, or a boolean type field from the source table of the form. If you have a field called "Blocked", you don't need the single quotes. If the field has a name with a space in it (like "This is Blocked") then you DO need quotes, but they need to be double quotes.

So, either set the SourceExpr to a boolean type field, or a boolean type variable (that is declared in your globals).
