Hi thanks for that, ive followed Emre’s guide but it still doesnt work, however ive decided to use fast payment buttons that take payment and close the ticket then show a message box with the change due. Ive set the payment buttons up but I cant seem to get the message box to appear to show the change. Ive tried the equation set up by John S:
but this displays the message box but the equation doesnt work
as im using this instead the red banner wouldnt appear as ive set the fast payment buttons to close the ticket after payment is made, do you have any suggestions for why my change box doesnt display the change due value?
Hi Guys, I’m having problems, I’ve got this far but I can’t get the message to appear, is there something missing from these instructions because I’m stumped !
Hello @helitrooper. While posting 11 months old topic it will be better to give some information about your context otherwise we should read 64 posts from beginning just to understand what you’re talking about.
Hi Emre, apologies for being a little vague, I’m trying to set up faster payment buttons and have followed all the earlier instructions, I have no problem setting up the buttons and I was following all the actions & rules shown in the earlier posts above but I cannot get them to do anything, furthermore since trying to set them up the ‘halfpint’ button that I had set up and got working has since stopped working again, in my frustration I have deleted everything thatI put in and will have another go tomorrow a little earlier in the day when my mind is functioning better
Hi Everyone, I have been following the instructions here to set up Fast Payment buttons following the instructions given above in this question thread, and I have got them working and all the messages are now displaying correctly. But how do I stop it from giving me a minus change amount?
Example - sale comes to 6.00 - operator press 5.00 button in error and the change shows - 1.00
It would be better not to be able to press the 5.00 button if the sale value is higher than that amount, otherwise we could end up giving that minus sum back as change.
ok, I get what you are saying, but I’m not sure how to go about doing it. I have 4 fast payment buttons, 5,10,20 & 50, I don’t know how to change the rule so that it will work for all 4 buttons, or would I have to clone my rule when it is constrained for one value [ie 5.01] and make 4 separate rules, one for each value?
We also don’t know. How did you set it up? I’ve browsed previous posts to get an idea but multiple implementations discussed here and I’m not sure which one you’ve preferred.
Hi Emre, I went all the way back to post 8 and followed JohnS’ and it works ok, but does not stop me from getting a minus figure for change, if there is an alternative way or you can tell me how to add the necessary constraint to the command button to stop it being pressed when it is less than the ticket total I will be glad of your assistance, this is a fantastic pos system with many options and my programming experience is very limited but I’m getting there gradually.
OK great. When that post was written Pay Ticket action didn’t have tendered amount parameter. John tried to compile a quick solution until we implement that but if you keep reading because of similar issues to your’s I’ve quickly implemented that parameter and I’ve demonstrated different solution. You can find the sample database on this topic.
Also if you search forums there are a lot of topics that demonstrates similar setup in detail.
