Unable to translate maximum product quantity validation message

Hi Team,

Am using “WooCommerce Max Quantity” plugin and I have set the “Maximum Quantity Limit Per Product” to 999 in Inventory settings.
I could get the validation message saying “Value must be less than or equal to 999” ,if I tried to add more that 999 products to cart.

But unable to translate this validation message using WPML.

Please help me to translate this text.
