Exactly.
[H2]="Ken" was an example as was the 2nd. All you need is the string assigned to the variable "s" in my code. The shell() would simple call "s" or use the string directly. e.g.
Shell "net use W: ""\\psych-files\finance"" /user:" & [H2] & [I2] , vbHide 'or vbNormal
When building strings for Shell() or other things like formulas, I like to assign a variable so that Debug.Print puts a run's result into the Immediate Window. Select the VBE menu View to enable that window if needed. It is a good way to well, Debug your code so that you know the resultant string value. Did you note how I commented the result of my run? I normally like to work it up manually and then I know the syntax needed for the string.
