Combing two different tasks into one program

[Michiel Spape]

Hi,
Just to voice my agreement with what David said before, as this 
"The problem is I did check through my procedure and my variable was defined and I wasn't missing any parameters."
This makes no sense from a programming point of view. E-Prime can be exasperating, but it is not a liar: your variable was not found as defined, and you were (i.e. your code was) missing parameters. 

Possibly, you wrote something like "Get attrib", (instead of, for example, c.GetAttrib("myAttrib") - mind that every little symbol is important here, except the casing, and that Get Attrib does not mean anything in EPrime) which would return something you describe, which sounds exactly like David's comment about running (writing inline, which people often find more advanced) before learning how to walk (understanding attributes, working with E-Prime basics). 

Sorry if that sounds needlessly mean; it is not my intention. If you want help from this list, here's a few tips:
- As said below: post an error, not summarise it and vainly hope people can make sense. Copy-paste the output, note the exact error number, and explain at what point it runs into this error.
- None of us has telepathic capabilities: explain the whole issue. What type of procedure are you trying to copy? Are you using EPrime 2? Does the procedure contain inlines, textdisplays, etc? Have you tried copying single objects (not procedures) instead? Where does the error occur? Start? End? Randomly? Or is it always the same line of inline code? If so, copy the code. I've never copied procedures between programmes, and I don't think it is even possible (but if it is, it wouldn't help much, because, all in all, the procedure itself is nothing but 'first do this' 'now do this'). Copying single objects (that define what 'this' is) is, however. It's a bit like forgetting the ORDER between the items of your shopping list isn't nearly as annoying as losing either the shopping list (i.e. the List object), or forgetting some items (textdisplays, etc). 
- Have a look at the getting-started guide/e-primer, etc. 

Cheers,
Mich

I kept receiving errors such as:

"error found during compile.

Get attrib:missing parameters.

Variable not defined"

The problem is I did check through my procedure and my variable was
defined and I wasn't missing any parameters. I don't think I had any
items that were the same name between the tasks. I'm sure pasting the
procedure inside another task can cause problems but I'm just not sure
where to look since it looks like I have everything I need to run both
tasks.
