If using XL97, macro security is on or off, no levels. If using newer version
of Excel have a look at the following.
Before setting your security to "low" which will let every file with macros
open without warning I would investigate the use of Office's Self
Certification tool.
You can create a digital certificate and use that on your VBAProject so only
that file with the certificate is allowed to be opened with no warning.
You can get to SelfCert either of these ways........
1. Start>Programs>Microsoft Office>Tools>"Digitasl Certificate for VBA
Projects"
2. Open Windows Explorer and drill down to your Office folder. Find
SelfCert.exe and run it.
This certificate is good only on your computer but can be used for more than
one file.
Once the certificate has been created and with your file open, go to the
VBEditor and select your VBAproject/file.
Tools>Digital Signature>Choose. Select the Certificate you just created.
OK your way out and save your file. You will repeat this step for each
workbook that contains macros.
Next time you open this/these particular file(s) you will not get the warning.
