Solved: Using variables in Forms!frmName.controlname etc

I use this vba in a form to set a textbox background on another open form like this;
Code:
Forms!frmsummary.[time line wills].Controls![txtdGuard].BackColor = vbYellow

This works fine of course.

Now the challenge is to use variables for the subform and control names.

Code:
dim subformname as string
dim controlname as string
subformname = "time line wills"
controlname =   "txtdGuard"
Forms!frmsummary.(subformname).Controls!(controlname).BackColor = vbYellow
This last line throws a 2465 error - app or object defind error

Any ideas please?

Firstly you don't need to refer to the controls collection ie you can omit it.

Forms!frmsummary.[time line wills]![txtdGuard].BackColor = vbYellow

On the subform, you need to refer to its Form collection.

Forms!frmsummary.(subformname).Form!(controlname).BackColor = vbYellow

Thanks for the quick reply. Your syntax for the subform is correct but only if I replace the two string variables with the actual subform and textbox names
Code:
Dim subformname As String
Dim controlname As String
subformname = "time line wills"
controlname = "txtdGuard"

Forms!frmsummary.[time line wills].Form![txtdGuard].BackColor = vbYellow ' this does not cause a syntax error and works BUT 
      'Forms.frmsummary.(subformname).Form!(controlname).BackColor = vbYellow ' this causes a syntax error in the IDE

So I still have the question - how do I use variables in the above commands. I need to do this so I can loop through all the controls on subforms in a tabbed control looking for empty text boxes, however for now I have simplified the above just to see if it is working with variables.

My mistake. Leave out the exlclamation mark and dot when referring to control names held in variables.
Forms.frmsummary(subformname).Form(controlname).BackColor = vbYellow
