[jason]

How do I seperate the "chk_" and "33" in the following string:

chk_33

Thanks Jason

dim ar, str
str = "chk_33"
ar=split(str,"_")
'ar(0) contains "chk"
'ar(1) contains "33"

Thanks - but I cannot do it that way because I may have other form values
seperated by an "_" underscore eg: "address_1"

My form collection will be returning:
chk_69
chk_33
chk_32
etc
txt_12
etc

....I don't think that function will do the trick?

...I should rephrase that:

When I iterate the form collection I need to isolate all the controls which
have the prefix: "chk_"

....and then complete the seperation - is this possible?

Can't you control that, and *not* that character for other meaningless
separations?

If you really must support something like chk_address_1 then look at the
MID() and INSTR() functions.

Jason,

Most of your posts today relate to our original exchage. Please check out my
reply to you under the 'Re: Multiple insert - iterate form collection -
checkbox name dynamic?' thread. The rest of your queries will be answered
too.

Cheers,

Alan

So? ar(0) will contain "address" and ar(1) will contain "1"? What's the
problem?

My form collection will be returning:
chk_69
chk_33
chk_32
etc
txt_12
etc

Why not? You don't know how to use an If statement? Try this:

for each x in request.form
'check to see if a "_" is present:
if instr(x,"_")>0 then
ar=split(x,"_")
if ar(0) = "chk" then
'we have a winner - do what you want with the variable:
y = ar(1)
else
'do nothing
end if
end if
next
