I am having problems trying to use the mid command to get a substring of a 
value.  I have saved a string into var1 and am trying to take 2 substrings 
from it.  I check if it has a period (.) in it, and if it does, I want to 
save the value to the left of the period in one variable and whatever is 
to the right of the period in another variable.  Here is what I've done:

var1 = "1.45"    //Not really a constant.  Just used for discussion

PlacePeriod = Instr(var1, ".")
TotalNum = mid(var1, 0, PlacePeriod-1)
PartNum = mid(var1, PlacePeriod+1, var1.length)

Whenever I try to perform these lines, I receive the following error:

      Invalid procedure call or argument: 'mid' 

Can anyone tell me what I'm doing wrong or another way to do what I need?

Thanks in advance,
Chris

Try this:

PlacePeriod = Instr(var1, ".")
TotalNum = mid(var1, 0, PlacePeriod-1)
PartNum = mid(var1, PlacePeriod+1, len(var1))

Hi Mark,
   I tried this but I am still having an error occurring.  The problem 
actually occurs on the first mid() line.  It says that 'mid' is an invalid 
procedure call or argument.  I understand the problem with the length that 
I had, but I do not understand why the script will not allow mid.  Does 
anyone know how to solve this problem?

Are you using JScript?
(I notice that your first line uses JScript comments:
var1 = "1.45"    //Not really a constant.  Just used for discussion
)

If so, then Mid() is not a valid method. Mid() is VBScript. JScript using
SubStr():

Cheers

Chris:

Your problem is that for mid() function, the first index of the string is 
1, instead of 0. 

So change to 

TotalNum = mid(var1, 1, PlacePeriod-1)

It will work.
