Why does space appear in concatenated string?

Hi, I have the following line in my code:

strNodeID = rsTreeViewAdd(strParentFIeld) & "N" & rsTreeViewAdd(strSubField) & str(intSubUnitCount)

Each of strParentField and strSubField refer to 8 character text fields.  Based on the code above, I would expect to get:

 11107001N110420012

But instead I get:
 11107001N11042001 2
(ie, there is a space before the final digit)

Can anyone tell me how to get rid of the space?  I tried using + instead of &, but it didn't help.

There might be a trailing spa ce in the field itself. Try passing the value through Trim() first:
strNodeID = rsTreeViewAdd(strParentFIeld) & "N" & Trim(rsTreeViewAdd(strSubField)) & Trim(str(intSubUnitCount))

The str function includes a position for the sign (or space, when the number is not negative). You could use a different conversion using format:

strNodeID = rsTreeViewAdd(strParentFIeld) & "N" & rsTreeViewAdd(strSubField) & format(intSubUnitCount)

Why are you converting intSubUnitCount to a string?  The & is specifically a concatenation function it will not try to add numbers the way the + will.

Gentlemen, thanks for the quick responses; I've tried all of your solutions, and all of them work.  I'm a bit embarrassed I missed so many ways of fixing the problem...I've got a lot to learn.

What is the etiquette for assigning points?  I will probably use PatHartman's solution (leave intSubUnitCount as an integer) as the simplest, but since all of your solutions work, should I accept multiple solutions?
jmcgOwnerCommented:
You can split points or just give all the points to the one you consider the best answer. If you're using Pat's solution, none of the rest of us has much right to complain if you give all the points to that solution. Spreading the points can be a nice gesture, but it can get a little ridiculous sometimes.
tmreiterAuthor Commented:
Thanks again.  Since all of the solutions worked, I wanted to give at least a few points to each of you, although I've allocated most of them to PatHartman.

The direct solution is to use CStr():
strNodeID = rsTreeViewAdd(strParentFIeld) & "N" & rsTreeViewAdd(strSubField) & CStr(intSubUnitCount)

Yup, that works too.  

When looking at Cstr, I learned that Str includes a leading space for positive numbers, which I would not have guessed.
Gustav BrockCIOCommented:
That's one difference. Another is, that Str() accepts Null while CStr) doesn't.
