An element of type '' cannot be converted to 'chaine Unicode'

This error message has been found to occur when using code like this:

FOR EACH (data source)

...

END

To avoid it, use this instead:

HReadFirst(data source)

While NOT HOut(data source)

...

...

HReadNext(data source)

END

Here's working example

For/Each gave the error. While Not Hout() ran correctly.

// Rename PayCategoryType for Salary Sacrifice

HReadFirst(tmpTable)

WHILE NOT HOut(tmpTable)

       //FOR EACH tmptable 

       IF Contains(Upper(tmpTable.PayCategoryName),"GUARANTEE") THEN

              tmpTable.PayCategoryType = "SUPER EXPENSES"

              HModify(tmpTable)

       END

       HReadNext(tmpTable)

END
