On my invoicing page I have a macro that runs when a Tax Type is selected,
and it looks up the applicable tax rate and this is then used to calculate
the tax amount based on the net charge amount and create the gross charge
amount.
It works absolutely fine when used the first time round i.e. when first
creating a particular invoice.
However if we then go back into that invoice and need to edit the Tax Type
(perhaps the user got it wrong) then the macro fails as soon as the combo
to
choose a different Tax Type is used. We have to hit Halt twice in the
dialog
boxes that appear and then nothing has been calculated.
What can the problem be??
Thanks
