run time error 13 "type mis-match"

[burl_rfc]

The code below adds the next seqential number to a text box on a form.

Everything works fine until I get to the following line, after
execution of the line of code I get the "type mis-match error":-
NextSeqNumber = "MIR-" & strNum

If I remove the "MIR-" & and simple use the following, it works fine
NextSeqNumber = strNum

I checked the user form to make sure that the text box is actually a
text box and it is.

Anyone have an idea what's causing the error.

Thanks

You're trying to return a string with 'NextSeqNumber = "MIR-" &
strNum', but your function starts out as:

Public Function NextSeqNumber(Optional sFileName As String, Optional
nSeqNumber = -1) As Long

I would guess the problem lies with the 'As Long'.

Excel doesn't allow "-" in an object name. If you put a TextBox on a
UserForm manually and try to change the name to include a dash, it
responds with "not a legal object name."

Hth,

Your function NextSeqNumber returns a long.

Public Function NextSeqNumber(Optional sFileName As String, Optional
nSeqNumber = -1) As Long

You can not assign a string to it as a return value. You could make the
retunr into a variant of a string if you wish...

Jim,

Thank you very miuch for the response, by changing the Public Fucition
callout from "Long' to "Variant", did the trick.

Thanks again.
