add 2 strings numerically

[boxhead]

i have 2 strings: a value in an array and a variable from some xml.

I need to numeriaclly add them together, as they are both strings, using + doesn't work. I have tried cStr but it errors

what do I do?

cheers

Just tried adding 1 to one of the values and then minus 1 of the end, but it appears it an xml error. I have:

myVar=(xmlDoc.selectSingleNode("DataReturn/DataBatch").xml)

myNum=myArray(0) + myVar

but the page seems to always read the xml value fresh, rather then just setting myVar to the value of DataBatch - how can i sort this?

cheers

try with &
string3 = string1 & string2

[boxhead]

& is for concatenation not addition

xmlDoc.selectSingleNode("DataReturn/DataBatch").xml

is not a number, its a string representation of the node, so it's likely to be something like
"<DataBatch>22</DataBatch>"
or maybe even
"<DataBatch>22<childNode>somevalue</childNode></DataBatch>"

Try
CDbl(xmlDoc.selectSingleNode("DataReturn/DataBatch").text)
to return a numeric value of what's contained in some node

Don't forget to use Response.Write(thingie) if you're not sure about what (thingie) contains.

I also suggest you install the documentation from the latest MSXML object and refer to that!

CLng()
CDbl()
CInt()

???

I used CDbl because it'll work regardless of whether the number has decimals or not.

superstars!!!!

I am booked onto a course, so hopefully I will be able to learn a lot from that and stop asking what are probably stupid question!

I wasn't questioning your post, merely showing other type conversion functions - look at the post timestamps.

Huh, we keep doing that today.
