Compile Errors using String theory

[Richard I]

Hi,
 Im trying to use String Theory to test whether an entered email address is valid.
 I have this in the code
         st.SetValue(lemailaddress)
         if st.ContainsA('@') = false
         p_web.setMessage('Not a Valid Email address','',false)         
         loc:Alert = 'Your email address does not appear to be valid, and was not recorded, please retry'
          p_web.SetValue('retry','RecordClocking')
         end

It wont compile-
4 errors
Unknown procedure label
Field not found: setvalue
unknown function label
field not found: ContainsA

I do have String Theory Global Extention template loaded.

What have I missed ?
Cheers

Sounds as if you haven't created the instance you're trying to use.

Do you have a StringTheory object named st in the procedure where your checking code lives (or a global object with that name that you're using)?

Thanks Jane,
No
St  or St. ??
local variable?
what about the "containsA ?
Should that be also?

Cheers

Pardon me if I'm misreading your confusion, Richard.

You have the global template in your app.  Therefore, StringTheory is available.

But as with any other class/object-based code, you need an instance of it to work with.

When you create an instance in your procedure, then the methods st.SetValue, st.ContainsA, etc. will be available. 
(Assuming you've named your instance st  )

In the DATA section of your procedure (somewhere above the CODE statement), try inserting this line

st       StringTheory

so you're creating a StringTheory object in that procedure with the name "st". 
Then see if the rest of your code compiles.

Hope that helps.

Thanks Jane,
Got it.

perhaps the help files were not quite clear enough...
