crosstable faillure if header field is nummeric

[#1]

I have a prolbem with my flexible crosstable

If the header is a nummeric value he doesn't work.

Has anyone a suggestion to fix this problem?

For example

My table looks like

Header 1	Header 2	Header 3
0	10	20
10	45	67
20	46	89

The yellow field is my height header

If it has the value A for example, everything works. But with a nummeric value, he can't make my height dimmension

My script for the crosstable is like:

Sub SubCrossTable
     Directory;
     Temp_CrossTable:
     CrossTable(Breedte, Prijs)
     LOAD
     *
     FROM
     $(vExcelDocument)
     (biff, embedded labels, table is $(vExcelTab)$, filters(
     Remove(Row, RowCnd(Interval, Pos(Top, $(vBovenBegin)), Pos(Top, $(vBovenEind)), Select(1, 0))),
     Remove(Row, RowCnd(Interval, Pos(Top, $(vOnderBegin)), Pos(Bottom, $(vOnderEind)), Select(1, 0)))
     ));
    
    
     Prijzen:
     load
     '$(vProductGroep)'&'#'&'$(vUitvoering)'&'#'&'$(vCollectie)'&'#'&'$(vPrijsGroep)' as SLT_PrijsGroep,
     $(vPrijsGroep) as Hoogte,
     Breedte,
     Prijs
     Resident Temp_CrossTable;
     drop table Temp_CrossTable;
End Sub

Who can help me with this question.

Dirk
