Form Help

[Rory898]

I am looking for a piece of code or macro of some kind to decrease the value in a field each time the form is opened. i.e:

The amount in stock is 400


each time the form opens i want it to go down by 20

therefore it will be 400 then 380 then 360 then 340 etc

Thanks in advance for your help

Is the field in the RecordSource of the form you are opening?

[Rory898]

Sorry what do you mean record source?

It is linked to a stock table. Its not a calculated field or anything

[RuralGuy]

On the Data tab of the property sheet for the form is the RecordSource property. Does this point to the table you want to modify?

[Rory898]

yea it is pointing to the table

[RuralGuy]

You said each time the form opens. Is there only one record in the table?

[Rory898]

Theres 3 separate values in the table but i only want one of them to decrease by 20

[RuralGuy]

You can use the OnLoad event to change the field but it will be pointing to the first record in the table. Is there only one record in the table?

[Rory898]

There are 6 records in the table

Text Paintball gun Supplier Name
Number Guns In Stock
Text Overalls Supplier
Number Overalls In Stock
Text CO2 Gas supplier
Number Amount in Stock <-- this is the value that i want to change

[RuralGuy]

That appears to be a strangely designed table. Have you studied up on normalization yet? Are those 6 Rows in the Table or 6 Columns in one Row? Here's a starting link on normalization: http://support.microsoft.com/kb/283878

yeaaa but the table isnt related to anything else. I just made it for this purpose of a form. I could remove the Text rows.

so it would just be :

Guns in Stock:
Overalls in Stock:
CO2 in stock:

Would this make it simpler?

Rory,
The problem I'm having is you seem to have a table with one field (Column) that changes back and forth between a text field and a numerical field. You can not do this in Access unless the "Numerical" field is really a text field which is a waste of resources of Access. It sounds like you are running a PaintBall park.

[Rory898]

Yea it is a paintball system. Here is the table and form. I would be extremely grateful if you cud take a look at it.

[RuralGuy]

That explains a lot Rory, thanks. Why do you have the Text fields in your table? I doubt you will forget what the next field will contain and besides it has a name as well that tells you what it contains.

[Rory898]

yeaaaa it was pretty unneccesary. So do you think i should remove all the text fields? and then how would i get the co2 field to decrease by 20 when it is opened?
