How to collect many data from one column in gallery

[PTDamia]

Hi, I'm facing problem where I need to input many data in one column

This is the scenario I faced:

This is the gallery of case from SharePoint. When user choose big case or small case, it will navigate user to another page where user need to input value of part number of the case.

When user scan the part number, the value will automatically be inserted into collection below. but somehow, I can't solve the problem.

This is column in SharePoint. it didn't appear. Supposedly in one case, there's more than one part number (in collection). Is it possible to do? Thank you in advance and sorry for not include the code because it's too messy since it didn't work 😞

I forgot to mention that I'm not using barcode scanner Button since I'm using RF Gun device, so it's not required to use barcode scanner function. I use text input only.  Is the code below can be use in text input? because i got error in the code

Collect(colScanned,{PartNumber:Self.Value})

You can try to use it in OnChange property and change Self.Value to Self.Text other then that you need to collect scans to that collection

Not sure why that happening

add to button Big

UpdateContext({varBigBB:true})

to Button Small and button patch part number

UpdateContext({varBigBB:fals})

then use that variable in the visible property of all the cards associated with Big record just place

varBigBB

No error but when i click big button, it doesn't appear. This is my code, correct me if im wrong

OnSelect Small

OnSelect Big

Onselect Save to collection

Collection

Patch Part Number

Big visible property

@PTDamia  I ask You to add the code not replace you still need to have varTypeBB there

@PTDamia 

Your Big button code should look like this.

Navigate();
UpdateContext({varBigBB:true});
UpdateContext({varTypeBB:"Big"})

The patch Button needs to be inside of the form, or You will not be able to use Thisitem means Patch will not be able to find record you want to Update

[PTDamia]

Still can't figure it. How to patch button inside form? Still error in ThisItem

The varBigBB goes to the Visible property of this control, not to the Big Button Control that way when You press the Big button they will show up and when you press Small button they will be invisible
