VB Code:

Text1.Text = Val(strA) + Val(strB)

Also, if you are going to be adding these together, they should be declared as integers

VB Code:

Dim intA As Integer
Dim intB As Integer

Then, you wouldn't need to Val them.

THEY CAN'T BE DECLER AS AN INTEGER SINCE SOME OF THE NUMBERS COULD BE
1.3
5.5
ETC..

Declare them as Long, single or double then

A Single or a Double would return decimals. A Long will round to an even number.

oh yes youre right :blush:

Long will truncate to an integer, not round to an even number!

Right?

Wrong. If you have this statement

Long = Double + Double

The Double + Double would be rounded to the nearest integer.

Not all "Wrong"... ;)

Long does indeed round a number (I thought it truncated it :blush: ), but it doesn't necessarily round to an EVEN number (1.3 gets rounded to 1 - an ODD number).

Now I think we're straight!

:lol: Ok, I misspoke. Long doesn't round to an even number it rounds to a whole number (which is actually what I meant but not what I typed.)

The '+' serves to join (concatenate) Strings. However, If you want to concatenate Strings, then
the appropriate operator is the '&' (ampersand), noting the '+' will do the same. Hence, you got '11' and not a mathematecal add equaling 2. :)
