[PAYMENTREQUEST_PAYMENTACTION] => Sale
[PAYMENTREQUEST_ITEMAMT] => 12
[PAYMENTREQUEST_AMT] => 14.21

Should be:

[PAYMENTREQUEST_0_PAYMENTACTION] => Sale
[PAYMENTREQUEST_0_ITEMAMT] => 12
[PAYMENTREQUEST_0_AMT] => 14.21

In addition, your amounts don't add up. You're setting a maximum of 14.21, but everything together is only 7.41

L_AMTm (should actually be L_PAYMENTREQUEST_0_AMTm) is item-specific. PAYMENTREQUEST_0_ITEMAMT is the subtotal of al items PAYMENTREQUEST_0_AMT should be the total of everything added together.

E.g.

[SOLUTIONTYPE] => Sole
[LANDINGPAGE] => Billing
[L_PAYMENTREQUEST_0_ITEMCATEGORY0] => Physical
[L_PAYMENTREQUEST_0_QTY0] => 4
[L_PAYMENTREQUEST_0_AMT0] => 2.20
[L_PAYMENTREQUEST_0_DESC0] => ZajÄ…czek 1
[L_PAYMENTREQUEST_0_NAME0] => ZajÄ…czek 1
[L_PAYMENTREQUEST_0_CURRENCYCODE0] => GBP
[L_PAYMENTREQUEST_0_ITEMCATEGORY1] => Physical
[L_PAYMENTREQUEST_0_QTY1] => 1
[L_PAYMENTREQUEST_0_AMT1] => 3.20
[L_PAYMENTREQUEST_0_DESC1] => ZajÄ…czek 2
[L_PAYMENTREQUEST_0_NAME1] => ZajÄ…czek 2
[L_PAYMENTREQUEST_0_CURRENCYCODE1] => GBP
[PAYMENTREQUEST_0_PAYMENTACTION] => Sale
[PAYMENTREQUEST_0_SHIPPINGAMT] => 2.21
[PAYMENTREQUEST_0_ITEMAMT] => 5.40
[PAYMENTREQUEST_0_AMT] => 7.61

Or the official PayPal example:

&L_PAYMENTREQUEST_0_NAME0=10% Decaf Kona Blend Coffee  
&L_PAYMENTREQUEST_0_NUMBER0=623083  
&L_PAYMENTREQUEST_0_DESC0=Size: 8.8-oz 
&L_PAYMENTREQUEST_0_AMT0=9.95  
&L_PAYMENTREQUEST_0_QTY0=2  
&L_PAYMENTREQUEST_0_NAME1=Coffee Filter bags  
&L_PAYMENTREQUEST_0_NUMBER1=623084  
&L_PAYMENTREQUEST_0_DESC1=Size: Two 24-piece boxes  
&L_PAYMENTREQUEST_0_AMT1=39.70  
&L_PAYMENTREQUEST_0_QTY1=2  
&PAYMENTREQUEST_0_ITEMAMT=99.30  
&PAYMENTREQUEST_0_TAXAMT=2.58  
&PAYMENTREQUEST_0_SHIPPINGAMT=3.00  
&PAYMENTREQUEST_0_HANDLINGAMT=2.99  
&PAYMENTREQUEST_0_SHIPDISCAMT=-3.00  
&PAYMENTREQUEST_0_INSURANCEAMT=1.00  
&PAYMENTREQUEST_0_AMT=105.87  
&PAYMENTREQUEST_0_CURRENCYCODE=USD
