Can Anyone help me in the following (Access 2010):
1. Dlookup("[KIT ID]", "[TOOLS]", "[BTN NO1] = "&[BTN SERNO])
2. Dlookup(("[KIT ID]", "[TOOLS]", "[BTN NO2] = "&[BTN SERNO])
3. Dlookup("[KIT ID]", "[TOOLS]", "[BTN NO1] = "&[BTN SERNO] or "[BTN NO2] = "&[BTN SERNO])
No.1 and No.2 is working fine. But No.3 when combining with "or" is not working. Where I am going wrong?
Note: Data Types [BTN NO1], [BTN NO.2] AND [BTN SERNO] Fields are Numbers.
Thank you in advance for your help.
Best regards
