Hi

I have a form which posts a series of orderid deliminated by a comma, the following code splits the order numbers

Dim arrRegistrants
 arrRegistrants=Split(Request.Form("orderid"),",")
 
I then need to get the 1st number of the orderid.. ie. if the order number is 400001 then i need 4 if it was 600001 then I need to get 6, so I added the following

DIM refid
refid =  LEFT ((arrRegistrants) ,2)
response.write refid

but I get this error
Microsoft VBScript runtime error '800a000d'
Type mismatch

any help appreciated

You are working in a Form class which has a Left property. The reason Left() returns an integer is because VB assumes you want to use the method/property that exists in the same, or closest imported, scope that you are working (hence, MyForm.Left, a property of the inherited class that you are working in, is more logical to assume than Microsoft.VisualBasic.Strings.Left()).

Try any of these:

Microsoft.VisualBasic.Strings.Left(Str, Len)
Microsoft.VisualBasic.Left(Str, Len)
Strings.Left(Str, Len)

HI sparky74,

The variable 'arrRegistrants' is an array, as specified by the use of the Split function. To use the Left function on a string in that array, you need to specify the index of the item....

    DIM refid
    refid =  LEFT ((arrRegistrants(0)) ,2)
    response.write refid

Regards,

Wayne
