Hi Tracy!
You could also use an assign-method; place the 'assign-property' as controlsource and the formula in the 'assign-method'.
HTH
>If a control has nothing in the controlsource but has a formula for its value i.e. m.prem1+m.prem2 refreshing the control does not run the formula again. Is there anyway to refresh those controls without restating the value as in this.txtprem_tot.value=m.prem1+m.prem2?
